This app is used to just list the COM ports that are available. I cant get it to display the list of COM ports.

use strict;
use Win32::SerialPort;
use Win32::GUI();

my $comport = 1;
my @list;
#my $comlist;

my $main = Win32::GUI::Window->new(

my $desk = Win32::GUI::GetDesktopWindow();
my $dw = Win32::GUI::Width($desk);
my $dh = Win32::GUI::Height($desk);
my $x = $dw / 4 * 3.25;
my $y = $dh / 4 * 2.5;
$main->Move($x, $y);

my $icon = new Win32::GUI::Icon('serialport.ico');
my $ni = $main->AddNotifyIcon(
    -name => "NI",
    -icon => $icon,
    -tip => "SerialPort Finder"

$main->AddLabel (-text => 'COM Ports Active:');

        );

$main->AddTimer( "com_list", 1000);
