The Avatex 1200-baud modem comes with an RS-232-C serial port, which should
work with any computer which supports a serial RS-232 port.  The Avatex modem
has a bank of switches on the back which allow you to "assert" (set to logical
"1" or "true") several of the standard control lines such as DATA TERMINAL
READY (DTR) or, alternatively, let your program control them.  What this means
is that if your program does not set these lines up properly, you can still
get the modem to put out a carrier by setting the switches properly.  I found
this handy with my Atari 800XL when one of my terminal emulators didn't seem
to turn on the carrier.  I now routinely leave DTR asserted by the modem
switch, as I am not likely to turn on the modem without the computer.

I don't know much about modems with parallel ports.  Usually the port
controller does the conversion to serial, not the modem itself, I thought.
