I have an old, old, old USR HST 9600.  It is the original type that 
makes loud clicking noises when it dials, and has the 300 baud backchannel.
I am attempting to use it with my new Esix (unix sysVr3) system.
It seems that I can get it to either work at 9600 baud, or at a lower
speed, but not both.  I have tried it both with the speed locked
and with it unlocked.  The problem I'm working on right now is to get
it to accept either user or uucp inbound calls.  When the speed is
locked at 9600, a 9600 can connect just fine -- but a 2400 caller gets
only garbage.  When the speed is not locked, 2400 callers can get it
(usually, but not always), but 9600 callers have garbage.

I know this isn't the optimal modem for this application .. but I can't
afford a Telebit right now (and they have big problems with low-speed
modems trying to connect).  What I'd like to find out is will this old
HST work at all for this application?  Am I wasting my time fiddling with
it?  I understand that the transmission rate is best when the speed is
locked ..  but am willing to forgo optimal speed to just get it to work
at both 9600 and 2400.  

various things to consider ...

gettydefs:  should it be allowed to cycle, or should it be locked in to
one speed with the modem handling the different call-in speeds?

inittab:  At what speed should uugetty init the modem?

register settings on hst:  I've used the modem on a dos bbs and it worked
fine (but ONLY with the speed NOT locked) ... I never have had success
with it locked.  

Any suggestions would be welcome.  If it won't work, I'll just lock it
at 2400 and forget about 9600-HST ... and get a Telebit as soon as I 
can (anyone have one for sale at a good price?)
