~ Lute,
  You're right... if the DSR on the 6551 ACIA is permanently tied to the
enabled position, then what I described is not the problem.  Since another
modem works fine, your best bet is to use the one that works until you upgrade
to a faster modem.  When you do upgrade, I'd recommend an "AT" command set
compatible modem.  I'd recommend you stay away from the cheapest fast modems,
but there's no need to go out and buy the most expensive, either... unless you
absolutely need 100% Hayes compatibility.
  Bruce PS:  I just threw in that "recommendation" because I saw your message
asking Bill Dickhaus what modem to get.  With most of the modems I've seen you
get pretty much what you pay for.  The cheap modems often have problems with
noise that wouldn't bother a better (more expensive) modem, while the really
expensive ones don't perform all that much better, at least not as much as you
might expect from their substantially higher price.
