I don't think you got good advice here from Dave.
You use a Palm OS Service to setup the connection and the OS takes care of dialing-up and make the connection for you. This also provides the user interface to do thing like entering the phone number, and specifying login parameters, etc., etc.
Writing your own modem handler is definitely a good example of doing things the hard way while re-inventing the wheel, ..... and any other cliche you can think of.
Though you may have such a non-standard problem that that's the only solution.

Is there any big trick to doing the initial handshaking between devices, or would it work to simply connect at a very slow rate and use standard methods to make contact? Also, do you know how to address the issue of generating DTMF tones? The Palm device would need to phone home and recognize whether a connection is made before it starts reporting.
Thanks for the help!

AFAIK, there are no Palm OS modem APIs. So I would just send the AT commands directly to the serial port. If you search the web, you may be able to find some open source routines that already do it. However, the AT command set is very simplistic, it wouldn't take much effort to write your own routines. I haven't worked directly with a modem in a while but from what I remember, it very easy.
