Would it still be possible at very low baud rates? 1200 baud is probably a lot more than I think I would need.
Mike: Suppose I wanted to send a fax at the lowest supported baud rate. I don't know much about the technological or programmatical differences but I'm just looking for something that will support the most basic communication (for example, sending a string of characters to a remote computer's terminal window or sending a fax that prints a sentence).
Haven't been able to find any audio mapping thus far but as long as I have that, i can probably write my own library to carry it out.
I should also add that beyond the basic handshaking that's needed to sustain a connection, I don't really want to receive anything. All the receiving is to be done by the hardware that is properly designed for it (real modems and fax machines, etc.)
