how to convert socket in linux to work on windows

[bamusic]

I have a perl script for unix which uses a socket to read data from gsm modem connected to com port.I need to convert it to windows.I think most of the script is going to be same except the line which establishes the socket connection.
Could someone please help me to know which lines I should change so that it will work on windows.
Here is the script
#!/usr/bin/perl -w

# TRG: Perl script to exercise GSM card through a set of diagnostic commands
# The results from each command are sent back to the browser client
# Accesses the GSM card via gsmd socket (for sharing)

use strict;
use IO::Socket::UNIX;
use Term::ReadKey;
use IO::Select;
use CGI qw(:standard);
use CGI::Carp qw(fatalsToBrowser);

# Keep Apache happy with the content
print "Content-type: text/htmlnn";

# Open the socket connection to GSMD
my $sock = new IO::Socket::UNIX (Type => SOCK_STREAM,
Peer => '/home/glucose/gsm/gsmd_sock',
Timeout => 60) || die "Couldn't establish socket: $!";
$! = 1;
my $s = IO::Select->new();
$s->add($sock);
$sock->autoflush(1);
ReadMode 4;

# Display suitable HTML headers and send a series of commands

#print "GSM Card Diagnosticsn";
sendcommand($s,$sock,"at+cerrn",'Last Error Message','');

# Close the socket connection and were done
$sock->close();

exit;
