The very first modems were essentially a speaker and a microphone that were connected to the telephone reciever by a couple of rubber cup-like things. > I was trying to find > some info but failed (perhaps I was looking at wrong places). > Is there a kernel module available that can turn soundcard into > modem? it wouldn't be a kernel module, but rather a simple program that would generate the right sounds over the sound card. In fact, in my old c-64 days that was exactly how we generated touchtone dialing. You simply instructed the sound system to generate the DTMF frequencies and they were sent over the phone lines. For use in a linux system, I would imagine your best bet is to have the program create the device node like a real modem would, capture the data from that and convert it to the appropriate sounds. You'd also want to emulate the at codes as well. It sounds a royal pain to me... better to just get a modem. A
