Yes.

More than that, there's no way for a modem to send a ring signal. Is
there? Is there an AT command which sends a ring signal?

A crossover or null modem cable. Or are you telling me to loopback the
DTR/whatever lines so the system gets it's own signal back when it looks
for a DCD?

I need the modems to answer first. A null modem cable would work
(perfectly), but there aren't serial ports free on one of the comps in
question.
Dammit, I'm always one piece of hardware short of what I need!

That has a faint chance of working, after making a connection with
chat/minicom or whatever.

Yes.
So my problem has been reduced to these choices:
1. Get a null modem cable.
2. Make a modem produce a ring tone. *quack*
3. Moo.
