	The problem does not really seem to be in the hardware.  It seems
to be an incompatibility between uugetty and the Hayes modem.  I have added
a couple of UDS 212A/d modems as bidirectional ports/ACU's and they are
working fine.  I stuck a datascope on the port and what seemed to happen
was with a Hayes modem on the port, uugetty running, CD (pin 8) held hi, and
a call coming in, uugetty sent a garbage character to the Hayes, which 
caused the Hayes to promptly hang up.  This happens with a Hayes 1200B, a
ARK 2400 and a USROBOTICS Courier, all Hayes compatible.  The UDS modem
eats the garbage and keeps on ticking.  It is NOT Hayes compatible.  I
am going to be going with 2400 baud modems with my news feed, so I will have
to get the Courier working.  I am going to play around with the Dialers file
and will let you know what I come up with.
	I have talked with a person at AT&T hot line, and he indicates that 
there is a software fix for the ports board hangin up with dtr off, but it 
is a cost upgrade.  This is my personal system, so I guess I will have to 
pay bucks for AT&T's mistakes..
