Hooking a Mac up with a modem is actually very simple.  The db9
connectors are readily available and if you have any skill with 
a soldering iron a db9 <-> db25 adapter will take about 15 minutes
to put together.  The connector just uses a reduced number of the 
rs232 signals, not a completely different interface.

One of the early issues of ST.Mac had a diagram
showing which pins on the mac side went to which pins on the modem
side.  Using this diagram I made a cable by substituting the appropriate
db25 pins for the corresponding db9 signals (on the modem side).
If anyone is interested I can post the specifics.

The Apple modem is (as I understand from rumors) a Hayes compatible,
so all it does to dial is transmit the appropriate Hayes command to
dial.  I have a U.S. Robotics modem that works fine with the pre-release
MacTerminal.
