Very Computer

I have some Term problems. I have a 14.4k modem.  I am able to make a 38.4k
connection with the Decstations at work.  If I set baudrate to 2400 in the
termrc file, everything works.  I can start term, run trsh, txconn, set the
DISPLAY, and start X programs.  Tupload works in both directions.
If I set baudrate to anything higher than 2400 (ie 2401),  I can still start
term, run trsh, txconn, and set up the DISPLAY, but I can't run any X stuff.
Tupload works from remote to local, but not from local to remote.
All I get under either failure is "timed out at x trans y" and y keeps going
up.  One odd thing is that when I try to start an X prog (xclock for ex.), the
send and receive light flicker for a second, then nothing and the timed out
messages start.
I bought a serial card with 16550A's on it since several people suggested that
was the problem, but it didn't change a bit.  The ports are recognized as 16550's on bootup.  As a test, I sent a file from remote to local using zmodem, and
sure enough, it did not drop characters when the machine sync'ed.  However,
it did have lots of problems sending a gzipped file.  I have a feeling that
the two problems are somehow related.
I believe everything is escaped correctly, I know
it is an 8 bit line, baudrate is not set too high.  Any help would be
greatly appreciated.
Do I have to put the modem in some strange mode before dialing in?  What combo
of v42, MNP, handshaking, etc seem to work?
My system:
        14.4k external Turbomodem Plus
        16550A Uarts
        kernel .99pl13
        Term 1.08
Thanks

The symptoms you describe are classic ones of a lack or failure of hardware
handshaking.  Something in the chain is not properly handling rts/cts flow
control.  It could be the remote modem, the modem cluster (or the serial
port if it is directly connected) or your local modem.  The most important
setting is at&\q3 on the 3 v.32bis modems I have access to.  CD should
track, usually at&c something. 1 ?  I set it at&c3 to reset the modem each
time it hangs up.  There is a possibility that the person who set up the
dialin did not set it right, but make sure you understand the settings on
your end first.
