If I understand you correctly, you want something from the modem that tells
your application to answer with the modem.  As far as I know, the only way
to do this is to set up your modem for auto-answer, then go away and poll
the carrier detect line for the connection.  Not exactly the thing to do (IMHO)
on the Mac and with the serial ports, since you're still tying up the port
with the modem and the polling.  However, if you just want it to sit there and
wait for a call, then the CTB and the Modem Tool should work fine.
