Is it possible to have a software modem communicate over the speaker / microphone ? I'm thinking of setting minicom to use /dev/dsp or something like that. Is this possible?? I want to get 2 pc's to communicate plugging ones speaker output into the other's microphone's input.

I've been able to recreate a crude modem like language to send and receive data (using ruby) but the modem language is a standard, also if possible I want the ability to have 3rd party software talk over an internet with ip addresses

i posted to an earlier post of yours. I hope this solves or atleast helps. Kind Regards

thanks you
