There is one other slight problem here. A null-modem cable is used
for connecting two rs-232 ports together when you're NOT using
modems.

You ARE using modems, so what you need is a "null-telephone company"
cable. You know, a cable that will produce a dial tone when ph0 goes
off-hook, then decode the tone sequence it receives, then produce a
ring signal to the other ph0, etc..... :-)
