This module makes it possible to use Perl programs that were written to use Win32::SerialPort or Device::SerialPort on the other kind of operating system without changing the source text. Just include the module and run your existing code:
It aliases the symbol table and provides a translating constructor.
Save it as AnySerialPort.pm somewhere on your Perl @INC path.
# Lets serial port programs written for either Windows or Unix
# work on the other kind of system without modification.
# By Ned Konz, ned@bike-nomad.com, http://bike-nomad.com
# This script must have only LF line endings to work cross-platform.
# usage:
# perl -MAnySerialPort myProgram.pl
#
# This will map port names between Linux and Windows; if your system d
+oesn't
# use the same mappings, you can call
# Device::SerialPort::mapPorts
# or
# Win32::SerialPort::mapPorts
# to change it:
# Device::SerialPort->mapPorts('COM1:' => '/dev/magicSerial0',
# 'COM2' => '/dev/magicSerial1');

we would like to use this in our (Perl-licensed) application but would like to be sure that your code has the same license since you did not state anything above or your home node...
bikeNomad hasn't been in these hallowed halls in the last decade and is therefore unlikely to see your message. His contact info is on the home node and his website (and at the top of this thread too). HTH.
If you're open to using modules from CPAN, you can check out Control::CLI. For serial port connections, it will use "Win32::SerialPort or Device::SerialPort for Serial port access respectively on Windows and Unix systems". That let's you write one code that can be used on either platform. And the module's author does include license and copyright information in the documentation.
And there's a chance that you might get better support (like bug fixes) by using the CPAN module than using bikeNomad's code posted on this site.
Just tossing out an alternative for you to consider.
