I've got a similar question, actually. I'm runing SCO Xenix 2.3.2 on
a 12 MHz 80286. When testing with a V.32 modem and the FAS driver
(using a 16550 with the buffer turned on) I'm only getting about 450
cps. Things seem to be configured correctly, so I'm at a loss to see
what could be causing this. Could it be that my CPU just doesn't have
enough oomph to work faster?
I'd appreciate any comments or experiences that anyone can share.
