I can't help with your original question of how to make Call Waiting *work*
when you're using your modem, but you may be able to *disable* Call Waiting
while you're on the computer.  This seems to vary quite a bit by area,
depending on what type of telephone company switches and what-not you're
connected to - Ask your phone company about the "Cancel Call Waiting"
service.  On my phone, I can dial either *70 tone or 1170 rotary (or tone)
to disable Call Waiting for the rest of the call.  After dialing this, I
get a second dial tone, suitable for a "pause" in dialing from the modem.
In other words, my dial string looks like this:

	ATDT1170,7894321

Since I can't have my modem dial *70 tone, I use the 1170, then a ',' to
wait for the second dial tone, then the phone number.  Hope this helps...
