I just picked up an old BellSouth 212A modem, and don't know how to make
it go.  It has a handful of pushbuttons on the front (AL ST RL DL HS TLK),
and doesn't respond to the Hayes command set.  Am I supposed to dial the
phone myself, and then tell the modem to wake up when I hear the carrier,
like with the old acoustic modems?  Any ideas on what those abbreviations
are?  I'm guessing HS = "high speed", probably meaning 1200 baud.  :-)
And TLK must be "talk".  The others have me stumped.  Maybe AL is "analog
loopback"?)
Hints would be appreciated.
        Thanks,
        Bill.
