You might want to check out the Win32::SerialPort module. I have a
script that uses it. The documentation describes how to create your
.conf file.
Here is part of it, to give you an idea:
###########################################
use strict;
use warnings;
use Win32::SerialPort;
my $comread;
#$serial is a Win32::SerialPort object that represents the comport.
#The line below declares it and ties it to the file handle INFILE
#using the configuration file HD_Queue.conf
my $serial = tie( *INFILE, 'Win32::SerialPort', "HD_Queue.conf" ) or
die("Couldn't tie! $^E\n");
#Infinite loop
while (1) {
#If there is data in the COM port buffer
while (<INFILE>) {
...etc.
