=head1 NAME
Win32::RASE - managing dialup entries and network connections on Win32
=head1 SYNOPSIS
use Win32::RASE;
=head1 ABSTRACT
This module implements the client part of Win32 RAS API.
It is named RASE(RAS-entry) because it was originally designed
to create/delete/change/manage RAS/DUN entries. Now it implements
synchronous dialing, hang up and the wide range of RAS/DUN
entry manipulations.
The current version of Win32::RASE is available at:
http://www.dux.ru/guest/fno/perl/
=head1 DESCRIPTION
This module is a collection of subroutines. As their names are very long
and specific and almost each corresponds to a Win32 API call I decided
to export a lot of them by default. Everything is exported except those
subs that are claimed as non-exported.
OK, you can C<require> it instead of C<use>.
B<!!! IMPORTANT !!!>
All functions (if the other behavior is not stated explicitly)
return TRUE on success, FALSE on error
to conform the handy calling rule
RESULT = function(PARAMS) or die MESSAGE;
where RESULT could be scalar or list either. Note that "||" is not
the same thing as "or".
The following logic is used: almost all functions croak on obvious programmer's
errors like invalid entry-name or such.
But they return FALSE and set LastError on internal API errors.
It is made to give the programmer a chance to complete all actions and may be
to trap some errors without exiting the program.
For example if some phonebook file is corrupted you have a chance
to try another one etc.
=over 4
The following two functions are available after any other function was executed.
They are both non-exported to provide feel and look of Win32-Perl built-in
functions with the same names.
=item GetLastError ( )
Returns 0 or the last encountered RAS, TAPI or Windows error number.
$lastErr = Win32::RASE::GetLastError();
Usually you should call this function after some other function
returned C<undef>. In case of Windows error it returns the same value as
C<Win32::GetLastError>. Unlike the built-in one it always returns 0
if the last called function finished successfully.
You can use it for example like this:
some_function();
Win32::RASE::GetLastError and die Win32::RASE::FormatMessage;
or implicitly
some_function() or die Win32::RASE::FormatMessage;
=cut
#================
sub GetLastError () {
#================
$LastError||0;
}
=item FormatMessage ( )
Converts the supplied RAS, TAPI or Win32 error number (e.g.
returned by C<Win32::RASE::GetLastError()>) to a descriptive string.
$message = Win32::RASE::FormatMessage($err_num);
Without the parameter assumes that the result of
C<Win32::RASE::GetLastError()> was sent.
=cut
#================
sub FormatMessage (;$) {
#================
my ($errnum, $buf) = (shift || GetLastError(), "\0"x1024);
$errnum =~ /^\-?\d+$/ or
RASCROAK "non-numeric value `$errnum'";
if ($errnum >= 600 && $errnum <= 750) {
$RasGetErrorString ||= new("rasapi32", "RasGetErrorString", [I,P,N], N);
my $ret = $RasGetErrorString->Call($errnum, $buf, length $buf);
$ret and RASERROR($ret);
CRUNCH($buf);
return "($errnum) $buf";
} elsif ($errnum == 751) {
return "(751) ERROR_INVALID_CALLBACK_NUMBER";
} elsif ($errnum == 752) {
return "(752) ERROR_SCRIPT_SYNTAX";
# TAPI LINEERR_* constants
} elsif ($errnum & 0x80000000) {
return "TAPI-error 0x".(sprintf "%8.8X",$errnum);
# TAPI PHONEERR_* constants
} elsif ($errnum & 0x90000000) {
return "TAPI-error 0x".(sprintf "%8.8X",$errnum);
# TAPI TAPIERR_* constants
} elsif ($errnum > 0xFFFF0000) {
return "TAPI-error 0x".(sprintf "%8.8X",$errnum);
}
"($errnum) ".Win32::FormatMessage($errnum);
}
=item IsWindow ( )
This function is non-exported for not to corrupt some other GUI related
synonym.
Win32::RASE::IsWindow( $hwnd );
Returns TRUE if $hwnd identifies an existing window, otherwise FALSE.
This function is handy to use before the functions that display a dialog box -
to verify the parent window.
=cut
#================
sub IsWindow ($) {
#================
my $hwnd = shift;
# to free dll right after the call (Dlg-functions are rare)
my $IsWindow = new("user32", "IsWindow", [N], N);
$IsWindow->Call($hwnd);
}

B< =====================================>
B< PHONEBOOK RELATED FUNCTIONS>
B< =====================================>
Note that by default all functions in this section work
with the default phonebook (on Windows NT).
The registry key C<"HKEY_CURRENT_USER\Software\Microsoft\RAS Phonebook">
has a dword subkey "PhonebookMode" which could have 3 values:
0 - the "system" phonebook is in use.
This is probably %SYSTEMROOT%\system32\ras\rasphone.pbk
1 - the "user" phonebook is in use.
This one is located in %SYSTEMROOT%\system32\ras\<filename>
<filename> here is the value of "PersonalPhonebookFile" subkey
that is located under the same key.
2 - the "alternate" phonebook is in use.
The full path to the alternate phonebook could be found in the
"AlternatePhonebookPath" subkey under the same key.
This version of C<Win32::RASE> provides no way to change these registry
settings. If C<"HKEY_CURRENT_USER\Software\Microsoft\RAS Phonebook\PhonebookMode">
is equal to 0 C<Win32::RASE> will use the "system" phonebook, in case 1 -
the "user" phonebook, in case 2 - the "alternate" phonebook.
The user can use the main Dial-Up Networking dialog box to create personal
phonebook files or change defaults (registry settings). The Win32 API does
not currently provide support for creating a phonebook file.
B<IMPORTANT:>
At any time you can set a global variable B<$Win32::RASE::PHONEBOOK> to the full path
of your phonebook file, and this phonebook will be in use until
B<$Win32::RASE::PHONEBOOK> is changed. Setting this variable to 0 or C<undef>
returns us to registry defined phonebook(s).
B<Windows 95/98:> Dial-up networking stores phonebook entries in the registry
rather than in a phonebook file. Windows 9x does not support personal
phonebook files. So B<$Win32::RASE::PHONEBOOK> has no meaning and must
always be C<undef>.
All functions treat entry-names as case-sensitive because RAS functions
are kinda semi-case-sensitive. Some of them fail when entry was given
with case-changes. But at the same time C<RasSetEntryProperties> API call
(in C<RasCopyEntry()>) fails to create both QWERTY and QwErTy, it renames
instead. Ou-h-h MS, MS...
The moral is: don't use names that differ only in upper/lower case.
There also is a danger in using multiple processes that are calling
RAS APIs that update the phonebook. Microsoft reported this problem
has been corrected in Service Pack 3.
http://support.microsoft.com/support/ntserver/serviceware/nts40/E9MSKWBJI.ASP
B<A note on multilink functionality>: there are no ways to use Multilink
programmatically on Win95/98. So, the current version of the module does not
support it for WinNT also. For more info read:
http://support.microsoft.com/support/kb/articles/q198/7/77.asp
Entry names for Windows CE cannot exceed 20 characters.
http://msdn.microsoft.com/library/wincesdk/wcecomm/ras_24.htm
A similiar problem is reported for the InternetMail Service (IMS) on
MS BackOffice Small Business Server version 4.5 and Windows NT Server version 4.0
http://support.microsoft.com/support/kb/articles/Q217/9/37.asp
So, the entries with long names may be unusable by the other applications.

=item RasCreateEntryDlg ( )
This function displays a dialog box in which the user types information
about the phonebook entry.
RasCreateEntryDlg( [$hwnd] );
$hwnd - handle to the parent window of the dialog box. Optional.
If you are using Win32::GUI this would be $Window->{handle}
As this is a synchronous operation and waits for user input it provides no
way to find out whether the new entry was created or not. You should use
C<RasEnumEntries()> to understand what has happened.
Here and everywhere in the functions that display a dialog box - if C<$hwnd>
is omitted or does not identify an existing window a dialog box is centered
on the screen.
=cut
#================
sub RasCreateEntryDlg (;$) {
#================
my $hwnd = shift;

my $ret = $RasCreateEntry->Call($hwnd||0, $PHONEBOOK||0);
$ret and ($LastError = $ret, return);
1;
}
=item RasEditEntryDlg ( )
This function displays a dialog box in which the user types information
about the phonebook entry. For a programmatical way to edit an existing
entry take a look at C<RasSetEntryProperties()>.
RasEditEntryDlg( $entry [, $hwnd] );
$entry - existing phonebook entry to edit.
$hwnd - handle to the parent window of the dialog box. Optional.
If you are using Win32::GUI this would be $Window->{handle}
This is a synchronous operation and waits for user input.
Croaks if C<$entry> does not exist.
You should call C<IsEntry()> before to verify C<$entry>.
=cut

$ret and ($LastError = $ret, return);
1;
}
=item RasRenameEntry ( )
RasRenameEntry( $oldname, $newname );
Croaks if C<$oldname> does not exist or C<$newname> already exists.
You should call C<IsEntry()> or C<RasEnumEntries()> before to verify both.
=cut
#================
sub RasRenameEntry ($$) {
#================

$ret and ($LastError = $ret, return);
1;
}
=item RasDeleteEntry ( )
RasDeleteEntry( $entry );
Croaks if C<$entry> does not exist.
You should call C<IsEntry()> or C<RasEnumEntries()> before to verify C<$entry>.
=cut

sub RasDeleteEntry ($) {
#================
my $entry = shift;

my $ret = $RasDeleteEntry->Call($PHONEBOOK||0, $entry);
$ret and ($LastError = $ret, return);
1;
}
=item RasEnumEntries ( )
@entries = RasEnumEntries();
This function lists all entry names in the phonebook.
As this function is heavily used internally it croaks on errors - for
example if non-existing phonebook name is given. So, FALSE result means
that the selected phonebook is empty.

=item RasSetEntryDialParams ( )
This function changes the connection information for a specified
phonebook entry.
RasSetEntryDialParams($entry, $UserName, $Password, $Domain,
$CallbackNumber, $fRemovePassword);
All parameters except C<$entry> are optional. C<undef> or omitted
parameters are considered to be "" - this means that no changes will
be made to this parameter.
$entry - name of RAS/DUN entry
$UserName - user name
$Password - password for the user specified by $UserName.
If $UserName is an empty string, the password is not changed.
If $Password is an empty string and $fRemovePassword is FALSE,
the password is set to the empty string. If $fRemovePassword is
TRUE, the password stored in this phonebook entry for the user
specified by $UserName is removed regardless of the contents
of the $Password string.
$Domain - domain on which authentication is to occur.
15 chars limitation.
$CallbackNumber - callback phone number
$fRemovePassword - (above) 0 if undefined/omitted
This is another excerpt from the API docs:
B<Windows NT:> You can use $Password to send a new password to the remote server
when you restart a RasDial() connection from a RASCS_PasswordExpired paused state.
When changing a password on an entry that calls Microsoft Networks, you should
limit the new password to 14 characters in length to avoid down-level
compatibility problems.

=item RasGetEntryProperties ( )
This function retrieves the properties of a phonebook entry.
$props = RasGetEntryProperties($entry);
$entry - name of RAS/DUN entry
$props - pointer to hash
The description of the %$props hash is common for this function and
C<RasSetEntryProperties()>.
KEY VALUE
name - copy of $entry
Flags - numeric flag value, combination of RASEO_* flags.
You don't need to use it directly, it's here for
information purpose only. In RasSetEntryProperties()
it is ignored if present, you should manipulate
mnemonic flags as described below, with the
'newFlags' key.
FlagsReadable - $props->{FlagsReadable} refers to array of
"mnemonic flags" that are affecting the behavior
of the other properties.
Not used by RasSetEntryProperties().
Manipulating these flags is described in C<RasSetEntryProperties()> section.
ipaddr - constant ip-address, ignored unless "SpecificIpAddr"
is present in the array of "mnemonic flags"
ipaddrDns - primary DNS server
ipaddrDnsAlt - secondary(backup) DNS server
ipaddrWins - IP address of the primary WINS server
ipaddrWinsAlt - secondary WINS server
C<ipaddrDns>, C<ipaddrDnsAlt>, C<ipaddrWins>, C<ipaddrWinsAlt> are
ignored unless "SpecificNameServers" is present in the array of "mnemonic flags"
All IP-addresses are in xxx.xxx.xxx.xxx decimal form without leading zeros
in each part(octet). For example: 195.100.0.28
The common rule here is that empty or blank values will produce 0.0.0.0
(as well as "0.0.0.0" itself).
CountryID -
CountryName -
CountryCode -
AreaCode -
(Country ID-Name-Code and AreaCode are described in the
C<TAPIlineGetTranslateCaps()> section except that here they are describing
the computer you want to dial to.)
In C<RasSetEntryProperties()>
C<CountryName> would be ignored. C<CountryID> not matching C<CountryCode>
would give error. You could easily give only one of these two values. C<CountryCode>
would be counted properly if C<CountryID> is given (described in
C<TAPIlineGetTranslateCaps()> section). But if you'll give C<CountryCode>
C<CountryID> would be set equal to C<CountryCode> that is sometimes incorrect
but does not affect the dialup connection.
You can also check the correctness of the C<CountryID> with the
C<IsCountryID()> function.
LocalPhoneNumber - phone number without country/area parts
Script - script file's path.
On Win95 this is DialUp Scripting Tool script.
Windows NT: To indicate a SWITCH.INF script name, set the first character
of the name to "[".
C<RasSetEntryProperties()> function may have a problem
saving the full script path (NT, fixed in the Service Pack 4).
http://support.microsoft.com/support/kb/articles/Q160/1/90.asp
DeviceType - one of the following string constants
(case-insensitive):
"modem" A modem accessed through a COM port
"isdn" An ISDN card with corresponding NDISWAN driver installed
"x25" An X.25 card with corresponding NDISWAN driver installed
"x25" type is not implemented in RasSetEntryProperties()
in this version of the module
"vpn" A Microsoft VPN Adapter
You can read a note about VPN and PPTP in the C<RasSetEntryProperties()> section.
DeviceName - name of a TAPI device to use with this phonebook entry
NetProtocols - network protocols to negotiate.
$props->{NetProtocols} refers to the array that can
contain one or more of the strings
(case insensitive in RasSetEntryProperties()):
"NetBEUI" NetBIOS End User Interface standard
"Ipx" IPX/SPX Compartible
"Ip" TCP/IP
FramingProtocol - framing protocol used by the server.
One of the following strings:
"PPP", "Slip", "RAS"
(case insensitive in RasSetEntryProperties())
B<Limitations:>
Subentries(multilink dialing) are currently not supported as well as X.25-related
parameters. Current version of Win32::RASE also does not allow you to change
'DeviceType' and 'DeviceName' elements. This will be added in some future.
Right now any changes in these fields will not affect the
C<RasSetEntryProperties()> execution.
B<Note:> don't misuse this function, in list context it returns
unreadable things for internal needs.
Croaks if C<$entry> does not exist.
For an easy way to change just the phone-number take a look at the
C<RasChangePhoneNumber()> section.

This function retrieves the properties of a device used by the phonebook entry
if this entry uses MS Unimodem compartible TSP (Telephone Service Provider) or
in other words - Unimodem compartible driver, on Win95 - always.
$props = RasGetEntryDevProperties($entry);
$entry - name of RAS/DUN entry
$props - pointer to hash
(Sorry, the description might not be clear enough, just print your
properties with the C<RasPrintEntryDevProperties()> and it'd be much easier.)
The description of the C<%$props> hash is common for this function and
C<RasSetEntryDevProperties()> (not implemented yet).
It's much likely that only a small part of the described data is
really usefull. Look at the Win32 SDK/MS Platform SDK
(TAPI Prorammer's Reference - "comm/datamodem", "COMMCONFIG", "DCB",
"MODEMSETTINGS" sections) for more info.
KEY VALUE
name - copy of $entry
DeviceName - name of a TAPI device to use with this phonebook entry
DeviceType - described in the RasGetEntryProperties() section
Options - numeric flag value, combination of the Option flags
that appear on the Unimodem Option page.
This member can be a combination of these values:
TERMINAL_PRE (1) - Displays the pre-terminal screen.
TERMINAL_POST (2) - Displays the post-terminal screen.
MANUAL_DIAL (4) - Dials the phone manually, if capable of doing so
LAUNCH_LIGHTS (8) - Displays the modem tray icon.
Only the LAUNCH_LIGHTS value is set by default
OptionsReadable - an array ref, a readable representation of those
Options, that are switched on. The array consists of zero or more
strings
"TERMINAL_PRE", "TERMINAL_POST", "MANUAL_DIAL", "LAUNCH_LIGHTS"
WaitBong - Number of seconds (in two seconds granularity) to
replace the wait for credit tone (default - 10 s)
CallSetupFailTimer - the maximum number of seconds the modem should
wait, after dialing is completed, for an indication that a
modem-to-modem connection has been established. If a connection
is not established in this interval, the call is assumed to have
failed. This member is equivalent to register S7 in Hayes
compatible modems.
InactivityTimeout - the maximum number of seconds of inactivity
allowed after a connection is established. If no data is either
transmitted or received for this period of time, the call is
automatically terminated.
This time-out is used to avoid excessive long distance charges
or online service charges if an application unexpectedly locks up
or the user leaves.
SpeakerVolume - one of the following values: "LOW", "MEDIUM", "HIGH"
Note that actual volumes are hardware-specific.
SpeakerMode - one of the following values:
"OFF" - The speaker is always off
"CALLSETUP" - The speaker is on until a connection is established
"ON" - The speaker is always on
"DIAL" - The speaker is on until a connection is established,
except that it is off while the modem is actually dialing
PreferredModemOptions - a numeric flag value. Specifies the modem
options requested by the application. The local and remote modems
negotiate modem options during call setup; this member specifies
the initial negotiating position of the local modem. A combination
of bit flags.
PreferredModemOptionsReadable - refers to array of strings that
represent bit flags of the previous. Contains zero or more of the
following strings:
"COMPRESSION", "ERROR_CONTROL", "FORCED_EC",
"CELLULAR", "FLOWCONTROL_HARD", "FLOWCONTROL_SOFT",
"CCITT_OVERRIDE", "SPEED_ADJUST",
"TONE_DIAL", "BLIND_DIAL", "V23_OVERRIDE"
Comments:
CCITT_OVERRIDE - When set, CCITT modulations are enabled for V.21
and V.22 or V.23.When clear, bell modulations
are enabled for 103 and 212A.
V23_OVERRIDE - When set, CCITT modulations are enabled for V.23.
When clear, CCITT modulations are enabled for
V.21 and V.22.
For V.23 to be set, both CCITT_OVERRIDE and V23_OVERRIDE must be set.
NegotiatedModemOptions - a numeric flag value. Specifies the modem
options that are actually in effect. This member is filled in
after a connection is established and the local and remote
modems negotiate modem options. This value is read only.
(On my Win95 - always 0).
NegotiatedModemOptionsReadable - the same ref to array of the readable
strings as PreferredModemOptionsReadable,
but for NegotiatedModemOptions.
NegotiatedDCERate - Specifies the DCE rate that is in effect.
This member is filled in after a connection is established and
the local and remote modems negotiate modem modulations.
Also read-only.
DCE - Open Software Foundation (OSF) Distributed Computing Environment.
The DCB structure defines the control setting for a serial communications device.
The following keys are members of the DCB structure.
DCB_BaudRate - Specifies the baud rate at which the communications
device operates. This member can be one of the following values:
110, 300, 600, 1200, 2400, 4800, 9600, 14400, 38400,
56000, 57600, 115200, 128000, 256000
DCB_Flags - numeric flag value, concatenation of many DCB flags.
You don't need to use it directly, it's here for
information purpose only.
DCB_FlagsReadable - an array ref. The array consists of the 13 string
values. Each string is in the form "flagname:value".
The values are in most cases 0/1. The flags names are:
fBinary - Specifies whether binary mode is enabled.
The Win32 API does not support nonbinary mode transfers, so this
member should be 1. Trying to use 0 will not work.
Under Windows 3.1, if this member is 0, nonbinary mode is
enabled, and the character specified by the DBC_EofChar member
is recognized on input and remembered as the end of data. (0/1)
fParity - Specifies whether parity checking is enabled (0/1)
fOutxCtsFlow - Specifies whether the CTS (clear-to-send) signal
is monitored for output flow control. If this member is 1 and CTS
is turned off, output is suspended until CTS is sent again. (0/1)
fOutxDsrFlow - Specifies whether the DSR (data-set-ready) signal
is monitored for output flow control. If this member is 1 and DSR
is turned off, output is suspended until DSR is sent again. (0/1)
fDtrControl - Specifies the DTR (data-terminal-ready)
flow control.
This member can be one of the following values:
0 - Disables the DTR line when the device is opened and leaves it
disabled
1 - Enables the DTR line when the device is opened and leaves it on
2 - Enables DTR handshaking
fDsrSensitivity - Specifies whether the communications driver is
sensitive to the state of the DSR signal. If this member is 1,
the driver ignores any bytes received, unless the DSR modem input
line is high. (0/1)
fTXContinueOnXoff - Specifies whether transmission stops when the
input buffer is full and the driver has transmitted the
DCB_XoffChar character.
If this member is 1, transmission continues after the input
buffer has come within DCB_XoffLim bytes of being full and the
driver has transmitted the DCB_XoffChar character to stop
receiving bytes.
If this member is 0, transmission does not continue until the
input buffer is within DCB_XonLim bytes of being empty and the
driver has transmitted the DCB_XonChar character to resume
reception. (0/1)
fOutX - Specifies whether XON/XOFF flow control is used
during transmission. If this member is 1, transmission stops when
the DCB_XoffChar character is received and starts again when the
DCB_XonChar character is received. (0/1)
fInX - Specifies whether XON/XOFF flow control is used
during reception. If this member is 1, the DCB_XoffChar character
is sent when the input buffer comes within DCB_XoffLim bytes of
being full, and the DCB_XonChar character is sent when the input
buffer comes within DCB_XonLim bytes of being empty. (0/1)
fErrorChar - Specifies whether bytes received with parity
errors are replaced with the character specified by the
DCB_ErrorChar member.
If this member is 1 and the fParity member is 1, replacement
occurs. (0/1)
fNull - pecifies whether null bytes are discarded.
If this member is 1, null bytes are discarded when received.(0/1)
fRtsControl - Specifies the RTS (request-to-send) flow control.
This member can be one of the following values:
0 - Disables the RTS line when the device is opened and leaves
it disabled.
1 - Enables the RTS line when the device is opened and leaves
it on.
2 - Enables RTS handshaking. The driver raises the RTS line when
the "type-ahead" (input) buffer is less than one-half full
and lowers the RTS line when the buffer is more than
three-quarters full.
3 - Specifies that the RTS line will be high if bytes are
available for transmission. After all buffered bytes have
been sent, the RTS line will be low.
fAbortOnError - Specifies whether read and write operations are
terminated if an error occurs. If this member is 1, the driver
terminates all read and write operations with an error status if
an error occurs. (0/1)
DCB_XonLim - Specifies the minimum number of bytes allowed in the
input buffer before the XON character is sent.
DCB_XoffLim - Specifies the maximum number of bytes allowed in the
input buffer before the XOFF character is sent. The maximum
number of bytes allowed is calculated by subtracting this value
from the size, in bytes, of the input buffer.
DCB_ByteSize - Specifies the number of bits in the bytes transmitted
and received.
DCB_Parity - Specifies the parity scheme to be used. This member
can be one of the following values:
"No parity", "Odd", "Even", "Mark", "Space"
DCB_StopBits - Specifies the number of stop bits to be used.
This member can be one of the following values:
0 - 1 stop bit
1 - 1.5 stop bits
2 - 2 stop bits
DCB_XonChar - Specifies the value of the XON character for both
transmission and reception.
DCB_XoffChar - Specifies the value of the XOFF character for both
transmission and reception.
DCB_ErrorChar - Specifies the value of the character used to replace
bytes received with a parity error.
DCB_EofChar - Specifies the value of the character used to signal
the end of data.
DCB_EvtChar - Specifies the value of the character used to signal
an event.
Manipulating these flags is described in C<RasSetEntryDevProperties()> section.

=item RasSetEntryProperties ( )
This function changes the connection information for an existing entry.
RasSetEntryProperties( $props );
$props - reference to hash with replacing properties
Mainly keys/values of the %$props hash are described in the
C<RasGetEntryProperties()>
section. But here we can use just part of the full hash - if keys are
undefined no changes will be made to the corresponding properties. Only
$props->{name} has to contain a name of the existing phonebook entry, all other
keys are optional.
Those properties that do exist in %$props will replace current properties.
If $props->{some-key} is defined and empty ("") the corresponding property
will be empty.
C<DeviceType>, C<CountryName>, C<Flags> and
C<FlagsReadable> keys are not used by this function. Anyway, all
unneeded keys will be ignored without any errors.
As of the version 0.07 you B<can> change the RAS device using with
the entry by specifying the new device name in $props->{DeviceName}.
The function finds the device type internally, so $props->{DeviceType}
is ignored if specified.
If "DeviceName" key is present in the C<%$props>
the function resets device properties for C<$props->{name}> entry to the
default values (for the list of device properties see
C<RasGetEntryDevProperties()>). C<RasEnumDevices()> function gives the
RAS-capable devices enumeration.
B<Microsoft has confirmed a possible problem>: With multiple modems installed under
Windows NT 4.0, the RasSetEntryProperties
API function calls will reset the selected modem to the first available modem.
This problem has been corrected in the latest U.S. Service Pack (4).
Print the whole enumeraton like this:
%devices = RasEnumDevices() or die "Error";
print map "\"$_\" of type \"$devices{$_}\"\n", keys %devices;
In addition to the keys decribed in the C<RasGetEntryProperties()>
section the string value
$props->{newFlags} can be used for adding/removing the existing flags
within the RAS-entry.
This string has the format: "<token1> <token2>..." (any C<\s> separators are possible)
Each token can be one of the following values (same as mnemonic flags
described in the C<RasGetEntryProperties()> section):
UseCountryAndAreaCodes
SpecificIpAddr
SpecificNameServers
IpHeaderCompression
RemoteDefaultGateway
DisableLcpExtensions
TerminalBeforeDial
TerminalAfterDial
ModemLights
SwCompression
RequireEncryptedPw
RequireMsEncryptedPw
RequireDataEncryption
NetworkLogon
UseLogonCredentials
PromoteAlternates
SecureLocalFiles
These strings are just the meaningful parts of C<RASEO_*> constants' names
(from "ras.h" file). They are rather descriptive, you can easily find
their meaning by changing and printing an existing RAS entry. Not
all of them will work in this version of the module.
Each of these flags could be used with or without the "RASEO_" prefix.
With or without
`+' or `-' prefix (no blanks between [+-] and "mnemonic flag") - this
is the token mentioned above.
Additional token that can't be prefixed with `+' or `-' is "KeepOldFlags",
it still can be prefixed with "RASEO_".
If this new flag-string ($props->{newFlags}) is C<defined> the default action
is to reset all old flags. "KeepOldFlags" prevents from this cleanup.
The token with `-' will reset the corresponding flag if it was set, otherwise -
no effect. The token with `+' will set the corresponding flag if it was not
set, otherwise - no effect. The order of tokens is not important, tokens are
separated by any number of blanks. Token without `+' or `-' means `+'.
Examples:
C<"NetworkLogon +SwCompression"> - reset old flags and add these two.
C<"-NetworkLogon -SwCompression KeepOldFlags"> - keep old flags and clean these two.
The function croaks if C<$entry> does not exist and on some impossible
values of the parameters.
B<PPTP note> (Point to Point Tunneling Protocol):
You can use an ip-address in place of LocalPhoneNumber if your DUN/RAS entry
is configured to work with VPN (Virtual Private Networking) via PPTP.
PPTP appears as a new modem type that can be selected in DUN entry only manually.
It DeviceName is "Microsoft VPN Adapter" and DeviceType is "vpn".
In this case you can change the ip-address of the
VPN-host as if it were local phone number. For example
RasSetEntryProperties({
name=>"NEV5",
LocalPhoneNumber=>"21.100.14.12",
});
You can get info about VPN and PPTP at
http://support.microsoft.com/support/kb/articles/q154/0/91.asp
DUN 1.3 that supports VPN is downloadable from
http://support.microsoft.com/download/support/mslfiles/MSDUN13.EXE
and is described here
http://support.microsoft.com/support/kb/articles/q194/4/77.asp
Thanks to Carl Sewell C<<>csewell@hiwaay.netC<>> for his explanations
and testing of VPN features.
B<Microsoft has confirmed the possible problem:>
After applying Service Pack 2, the RasSetEntryProperties flags for
RASEO_TerminalAfterDial and RASEO_TerminalBeforeDial specified in
the Win32 function call are not set. This problem occurs because
Service Pack 2 causes the parameters to be ignored.
This problem has been corrected in Service Pack 3.
http://support.microsoft.com/support/ntserver/serviceware/nts40/E9MSL2CSA.ASP
B<Microsoft:> When using the RasSetEntryProperties API call to change the connection
information for an entry in the phone book or create a new phone-book entry,
the szScript (C<$props->{Script}> in C<Win32::RASE>) parameter of the RASENTRY
structure is not always preserved.
http://support.microsoft.com/support/kb/articles/q160/1/90.asp
This problem applies to WinNT 4.0 and was corrected in the latest
Microsoft Windows NT 4.0 U.S. Service Pack (4).
The function croaks if the specfied device is not found.

=item RasCreateEntry ( )
This function creates RAS/DUN entry programmatically (note that
C<RasCreateEntryDlg()> displays dialo boxes).
RasCreateEntry( $props );
C<Win32::RASE::PHONEBOOK> defines the phonebook in which the new entry will
be created (WinNT).
For the explanation of the C<%$props> hash see the previous C<RasSetEntryProperties()>
function. The main difference is that these keys
name, LocalPhoneNumber, NetProtocols, FramingProtocol, DeviceName
are mandatory in this hash.
You have to specify at least one of CountryID and CountryCode keys and AreaCode
key if C<$props->{newFlags}> contains "+UseCountryAndAreaCodes".
All ip-addresses if omitted are assumed to be "0.0.0.0". Empty or non-existing
C<$props->{newFlags}> gives zero numeric flag which means that none of the
C<RASEO_*> options are in use. Flag "KeepOldFlags" has no meaning but makes
no error.
Note that the device settings would be copied from your system defaults and
some minor features still could not be customized (see C<RasGetEntryDevProperties()>).

or '+7 (095) - 5-5-5-5-5-5-5' or '7 095 5555555'
It is smart enough to adjust entry flags to avoid long distance dialing if

All other flags are kept unchanged.

=item RasGetProjectionInfo ( )
In the current version projection info is implemented for IP protocol only.
This is a subject to change.
($ip, $server_ip) = RasGetProjectionInfo ( $hrasconn );
$hrasconn - handle of the active connection returned by either
RasDial() or RasEnumConnections().
$ip - the client's IP address on the RAS connection
$server_ip - the IP address of the remote PPP peer (that is, the
server's IP address)
Both IP addrs are in "nnn.nnn.nnn.nnn" form.
B<From the API docs:>
Remote access projection is the process whereby a remote access server
and a remote client negotiate network protocol-specific information.
A remote access server uses this network protocol-specific information
to represent a remote client on the network.
B<Windows NT:> Remote access projection information is not available until
the operating system has executed the C<RasDial> C<RASCS_Projected> state on the
remote access connection. If C<RasGetProjectionInfo()> is called prior to the
C<RASCS_Projected> state, it returns C<ERROR_PROJECTION_NOT_COMPLETE>.
B<Windows 95:> Windows 95 Dial-Up Networking does not support the
C<RASCS_Projected> state. The projection phase may be done during the
C<RASCS_Authenticate> state. If the authentication is successful, the connection
operation proceeds to the C<RASCS_Authenticated> state, and projection information
is available for successfully configured protocols. If C<RasGetProjectionInfo()>
is called prior to the C<RASCS_Authenticated> state, it returns
C<ERROR_PROTOCOL_NOT_CONFIGURED>.
PPP does not require that servers provide this address, but Windows NT
servers will consistently return the address anyway. Other PPP vendors
may not provide the address. If the address is not available, this member
returns an empty string ("").
I guess the last note is probably outdated because my Advanced Dialer
has a field for "Server's IP address" - so, it expects that it's always available.
If you are using C<Win32::RASE> in a single process application you can't
monitor C<RASCS_*> states (for more info look at C<RasGetConnectStatus()>).
So, the rule is: use this function after C<RasDial()> successfully
returned C<$hrasconn>.
The typical usage if you have only one connection is:
unless ( $hrasconn = (RasEnumConnections())[1] ) {
print "Dialing sequence not started\n";
} elsif ( ($ip, $server_ip) = RasGetProjectionInfo( $hrasconn ) ) {
print "LOCAL:$ip SERVER:$server_ip\n";
} elsif ( Win32::RASE::GetLastError == 731 ) {
print "Protocol not configured yet\n";
} else {
die Win32::RASE::FormatMessage();
}
Note also that LastError=6 means that C<$hrasconn> is an invalid handle.

=item RasHangUp ( )
RasHangUp($hrasconn [, $timeout]);
$hrasconn - handle of the active connection returned by either
RasDial() or RasEnumConnections().
$timeout - in sec, optional (3 sec by default). Maximum time to wait
for graceful disconnection. You can use float values if
Time::HiRes is installed. Otherwise cycle uses sleep(1)
and thus wastes some additional time.
This function gracefully terminates the connection. You don't need to add any
C<sleep> after it.
The connection is terminated even if the C<RasDial()> call has not yet been completed.
After this call, the $hrasconn handle can no longer be used.
Returns FALSE if invalid handle was given but this is harmless
most of the time. Probably the connection failed itself and C<$hrasconn>
is not valid any more. So, you don't have to trap this error.
Returns FALSE on timeout also (connection might be still active). LastError
is 0 in this case. So the exact logic is:
if ( RasHangUp($hrasconn, $timeout) ) {
print "Connection is terminated successfully.\n";
} elsif ( !Win32::RASE::GetLastError ) {
print "Timeout. Connection is still active.\n";
} else {

=item HangUp ( )
This is the easier version of previous.
Without parameters it will terminate all active connections, otherwise
terminates connections by B<entry-names> given as parameters. Note that
this function uses entry-names, not handles.
$code = HangUp ( [$entry1, ...] );
Returns FALSE if at least one connection was not terminated gracefully,
otherwise TRUE even if no one active connecton was found.
Command line syntax:
perl -MWin32::RASE -e HangUp

=item RasGetConnectStatus ( )
This function is used to monitor active connection in progress. In most
cases it's good to cycle calls to this function after a very small interval,
say 0.1 sec or less - at least at the dialing time. It's possible in
multithreading process (thread safety is not verified in this version)
or one process can monitor another, which is closer to perl practice.
$status = RasGetConnectStatus($hrasconn);
or
($status, $status_text) = RasGetConnectStatus($hrasconn);
$hrasconn - handle to active RAS/DUN connection
In scalar context returns numeric status (RASCS_* enumerator values) or
FALSE if C<$hrasconn> is not a valid handle (LastError is set to 6).
In list context returns numeric status and the string that characterizes
this status in short (the descriptive part of the corresponding RASCS_ constant's
name, like "OpenPort") or FALSE if handle is invalid.
FALSE is also returned if handle is "not valid any more", i.e. connection
is terminated.
These string constants ("PortOpened" etc.) are stored in a non-exported hash
B<%Win32::RASE::RASCS> where the keys are numeric values of the corresponding RASCS_*
constants. So
$Win32::RASE::RASCS{1} eq "PortOpened"
You can check status yourself against exported RASCS_* constants:
RASCS_OpenPort
RASCS_PortOpened
RASCS_ConnectDevice
RASCS_DeviceConnected
RASCS_AllDevicesConnected
RASCS_Authenticate
RASCS_AuthNotify
RASCS_AuthRetry
RASCS_AuthCallback

RASCS_Interactive = RASCS_PAUSED
RASCS_RetryAuthentication

B<From the API docs:>
The connection process states are divided into three classes: running states,
paused states, and terminal states. An application can easily determine the
class of a specific state by performing Boolean bit operations with the RASCS_PAUSED
and RASCS_DONE bitmasks. Here are some examples:
$fDoneState = $status & RASCS_DONE;
$fPausedState = $status & RASCS_PAUSED;
$fRunState = !($fDoneState || $fPausedState);

=item RasDialDlg ( )
This function tries to establish a RAS connection using
a specified phonebook entry and the credentials of the logged-on user.
It displays a stream of dialog boxes that indicate the state of the connection
operation and returns when the connection is established,
or when the user cancels the operation. B<Windows NT only.>
RasDialDlg( $EntryName [, $hwnd, $PhoneNumber] );
$EntryName - RAS/DUN entry, the only mandatory parameter
$hwnd - Identifies the window that owns the modal RasDialDlg
dialog boxes.
This member can be any valid window handle, or it can
be 0, undef (or omitted) if the dialog box has no owner
The dialog box is centered on the owner window unless C<$hwnd> is C<FALSE>
or invalid handle, in which case the dialog box is centered on the screen.
$PhoneNumber - an overriding phone number (if not needed - use "" or
undef).
It does not inherit anything from phonebook if specified - no prefix,
no callin card, no waiting.
You should even add DP before the number for pulse dialing.
Returns TRUE on success, FALSE if user selects "Cancel" button or an error occurs.
You can check the last case with C<Win32::RASE::GetLastError()>.

=item RasDial ( )
This function establishes a RAS/DUN connection. The connection data includes
callback and user authentication information.
$hrasconn = RasDial($EntryName, $PhoneNumber, $UserName, $Password,
$Domain, $CallbackNumber);
$EntryName - RAS/DUN entry, the only mandatory parameter
$PhoneNumber - an overriding phone number (if not needed - use "" or
undef).
It does not inherit anything from the phonebook if specified -
no prefix, no calling card, no waiting.
You should add DP before the number for pulse dialing.
$UserName - user's user name (look below)
$Password - user's password
$Domain - domain on which authentication is to occur. An empty
string ("" or undef) specifies the domain in which the remote
access server is a member (NT only). An asterisk specifies the
domain stored in the phonebook for the entry.
It's in addr form (size is limited to 15 chars).
$CallbackNumber - a callback phone number. An empty string ("") or
undef indicates that callback should not be used. This string is
ignored unless the user has "Set By Caller" callback permission
on the RAS server (NT only). An asterisk indicates that the number
stored in the phonebook should be used for callback.
B<Windows NT:>
[These 2 paragraphs are copied from the API docs. I wanted to add this
for some completeness but I was told that probably this is not truth and if
Username or Password are empty user will get a dialog box with Username/Password
prompts.]
RAS does not actually log the user onto the network. The user does this in the usual
manner, for example, by logging on with cached credentials prior to making the
connection or by using CTRL+ALT+DEL, after the RAS connection is established.
If both the UserName and Password members are empty strings (""), RAS uses the
user name and password of the current logon context for authentication. For a user
mode application, RAS uses the credentials of the currently logged-on interactive user.
For a Win32 service process, RAS uses the credentials associated with the service.
B<Windows 95:>
RAS uses the UserName and Password strings to log the user onto the network.
Windows 95 cannot get the password of the currently logged-on user, so if both
the UserName and the Password members are empty strings ("" or undef), RAS leaves
the user name and password empty during authentication. I.e. it provides no
additional search (look at C<RasGetEntryDialParams()> for that).
B<Note:> It seems that overriding phone number is being dialed "as is" - without using
any long-distance/international phone settings. So you have to provide this number
with all prefixes and waitings (W etc.) if needed. Additional
dashes, blanks and brackets are OK.
$hrasconn - on success - handle to active RAS/DUN connection,
otherwise undef
You can use C<$hrasconn> in C<RasGetConnectStatus()> or C<RasHangUp()>.
Note that this function calls C<RasHangUp()> internally on error, so after that,
the handle of the failed connection is not available and the port is ready
for the next try.
B<Example:>
($err, $errtext) = RasDial("CLICK",undef,"ppblazer","qwerty");
if ($err) {
print "$err, $errtext\n"; exit;
} else {
... your work here ...
}
B<Last note:> this is the B<synchronous> operation. Nobody knows if it could really
hang fast enough if the line is busy (for ex.) The best way would be to run C<RasDial()>
in the separate process or thread. In most cases you don't really need C<$hrasconn>
in the main process - you can terminate the connection at any time with C<HangUp()>.
Or you can easily get C<$hrasconn> with the use of C<RasEnumConnections()>.
If you run C<RasDial()> in a child-process and terminate dialing in progress (for ex.
on timeout) you have to free the port yourself (C<RasHangUp()> or C<HangUp()>).
For more info take a look at Win32 API docs (RASDIALPARAMS etc).

=item RasEnumDevices ( )
%devices = RasEnumDevices();
This function returns the name and type of all available RAS-capable devices.
In the C<%devices> hash device names are keys and types are values. Common
device types are "modem", "x25", "vpn", "isdn", "rastapi" etc.
Croaks on errors. Returns FALSE if no one RAS capable device was found.
For example the first RAS-capable device name is
$DeviceName = (RasEnumDevices())[0];
This function fills out a non-exported hash C<%Win32::RASE::RasDevEnumeration>
of the same structure as C<%devices>, so in most cases there is no need to call
this function more then once.

=item TAPIlineGetTranslateCaps ( )
This function is not exported and is not intended for public use.
It is called each time you load Win32::RASE and fills out 3 global variables
and global hash (below).
It takes local information from your dialup settings.
($countryID, $countryCode, $areaCode) =
Win32::RASE::TAPIlineGetTranslateCaps ();
The return values are describing the B<Current Location> that is selected
in you dialing properties.
$countryID - the unique number that TAPI assigns to each country.
It is not what you are typing on your phone, though it
sometimes has the same value. Different countries always
have different countryID. This allows multiple entries
to exist in the country list with the same country code
(for example, all countries in North America and the
Caribbean share country code 1, but require separate
entries in the list).
$countryCode - this really is the code that would be dialed in an
international call to your computer's location.
$areaCode - city or area code (local).
These 3 values are copied to non-exported global variables
B<$Win32::RASE::LOCAL_ID>, B<$Win32::RASE::LOCAL_CODE> and
B<$Win32::RASE::LOCAL_AREA>.
They are mainly for internal use, just note that they are here.
The complete TAPI countries list is being copied to non-exported global hash
B<%Win32::RASE::TAPIEnumeration>. Keys are countryID's, each value points
to 3-element array: [0] is country-name, [1] is countryCode described above,
[2] is NextCountryID in TAPI-enumeration (TAPI docs, but in most cases you
don't need to use this hash explicitly).
Use C<TAPIEnumerationPrint()> to print this hash (for fun ;)

=item TAPIEnumLocations ( )
Just a handy function (non-exported) to enumerate locations in your Dialing Properties.
It's being executed internally when Win32::RASE needs it, so in most cases you don't
need to use it explicitly.
($CurrentLocation, %locations) = Win32::RASE::TAPIEnumLocations;
$CurrentLocation - current dialing location's name
%locations - keys are location-names, values are anonymous
arrays that are filled out like:
[$CountryID, $CountryCode, $CityCode, $Options, $LocalAccessCode,
$LongDistanceAccessCode, $TollPrefixList, $PermanentLocationID]
$Options - 0/1 tone/pulse dialing, this value could be
used to define good timeout for RasDial()
$LocalAccessCode - the access code to be dialed before calls to
addresses in the local calling area
$LongDistanceAccessCode - the access code to be dialed before calls to
addresses outside the local calling area
$TollPrefixList - the toll prefix list for the location. The
string will contain only prefixes consisting
of the digits "0" through "9", separated
from each other by a single comma
$PermanentLocationID - internal unique identifier of the location
Other values in array are described in C<TAPIlineGetTranslateCaps()>.
B<Example:>

This is a non-exported function mainly for internal use. It could be handy only
if you'd start writing your own TAPI-related functions.
($hLineApp, $dwNumDevs) = Win32::RASE::TAPIlineInitialize();
or in scalar context
$hLineApp = Win32::RASE::TAPIlineInitialize();
$hLineApp - the application's usage non-zero handle for TAPI
$dwNumDevs - number of line devices available to the TAPI application
Croaks on TAPI errors.
The applicaton should always call C<TAPIlineShutdown()> to release memory
resources allocated by TAPI.DLL.

=head1 INSTALLATION
As this is just a plain module no special installation is needed. Put it
into the Win32 subdirectory somewhere in your @INC.
This module needs Windows Remote Access Service (RAS) or DialUp Networking (DUN)
to be properly installed including dialing properties.
rasapi32.dll, tapi32.dll
Win32::API module by Aldo Calpini.
enum.pm (1.014 or later, no compilations) by Byron Brummer (aka Zenin)
Time::HiRes (0.18 or later) by Douglas E. Wegscheid makes work more precise.
=head1 CAVEATS
This module has been created and tested in a Win95 environment. Although
I expect it to function correctly on any version of Windows NT, that fact
has been confirmed for NT 4.0 build 1381 only.
Some of the RAS APIs were not included in the RasAPI32.dll that was shipped with
the old releases of Windows 95. To use the RAS APIs mentioned here, you need to install the
at least Dial Up Networking (DUN) 1.2b upgrade.
This upgrade is available for download on:
http://www.microsoft.com/windows/downloads/contents/Updates/W95DialUpNetw/default.asp
This upgrade was incorporated in Win95 OSR.
From the B<MS KB# Q157765>: Early releases of Windows 95 may require
an additional RNAPH.DLL that
contains some of new phonebook manipulation APIs. There currently is no
workaround for this situation in this version of the module.
Some APIs may also not work properly on WinNT with old Service Packs. Make sure that
you are using the last Service Pack available.
List of Bugs Fixed in Windows NT 4.0 Service Pack 1, 2, and 3
is available at
http://support.microsoft.com/support/kb/articles/q224/7/92.asp
What can we do here, guys? That's how it goes...
=head1 CHANGES
1.00 First public release
1.01 The only thing touched is Makefile.PL. The distribution is packed
now using UNIX conventions (LF only, unlike the 1.00 dist)
=head1 TODO
NT-only API: RasGetCredentials, RasSetCredentials, RasMonitorDlg, RasPhonebookDlg.
Any suggestions are much appreciated.
=head1 BUGS
