WHoo boy, do i have an interesting one here...I need to replace some ms-dos software that communicates to a barcode scanner via serial port, but I'm unsure of the protocol (if any) it uses. I'd like to use perl to help build replacement software so I can use said devices with win2k and/or linux.

Is there a way for me to, through perl, *listen* to the i/o of the serial port in a non-blocking manner (ie: not binding to the port)? That is to say, log to a file all input and output through the serial port, while still allowing any other program(s) to use the serial port at their leisure?

I just need to sit at the sideline and log the communications between the device and the client ms-dos program. Any help will be *greatly* appreciated
