I had several AT clones running Xenix in a past job.  We were using the
Computione Advantage X, 3mb ram, with a normal load of 6-8 users.  I never
really experienced a slow down problem that you mention, but I have a guess
at what you might try.

Since you are using a Computone board, you can just about turn off all the 
flow control {ie stty flags} that are set in the /etc/gettydefs file.  Right
now, IO has two processors doing the same job on the same data.  Not only is
that a waste of the power of the 80286, but it will actually cause
communication problems with uucp and micnet.  My advice for you is to 
tailor the gettydef entry for your computone.  The only *must have* stty
value for the entry is the port rate.

BTW, are you using the Computones at the max 38.4 Kb/s ?

A note for other Computone users:

To make micnet and uucp work on a Computone port, there must be no
flow control applied in the /atx/attype file.  An alternate fix is
to get a replacement driver form you VAR or direct from Computone.
