[fa.info-mac] foreign modems

I'm using a USR 212A Autodial modem on my Mac and it works just fine.  I
took the wiring instructions from the comments in one of the early versions
of MacTep.  Since the cable did not include a connection for DTR, I had to
set the 'DTR override' switch on the back of the Autodial to get it working.
The version of MacTep archived at sumex-aim should have instructions for a
more complete cable.  I believe the cable wiring to hook a Volksmodem to the
Mac can be found in database section 5 of the Apple SIG on Compuserve.

Since the modem works with MacTep, I know that it will work with MacTerminal.
The only question is whether MacTerminal's special features (on-screen LEDs
and Dial command) will work with the USR.  I don't care whether the on-screen
LEDs work or not since I have *real* LEDs on the front of the modem.  The USR
and Hayes use the same command for dialing the phone (yes, I know the modems
differ quite a bit in other respects), and it's probably a fairly safe bet to
assume that the Apple modem is based on either a USR or a Hayes.
