I've just got V1.3 (MINIX-PC) running.  The best performance I can get
from the the serial port (under Kermit, without losing *chunks* of
stuff in emulation) seems to be 300 bps (kermit won't believe 600
exists, and performance is lousy at 1200).  This is on a 10MHz XT-clone.

I am aware of some patches from Charles Hendrick (~3-OCT-88) which I have
yet to apply, and which may well imporove this situation.  But my question
is: what performance should I expect?  I haven't seen much (any?)
comment on this since V1.3 stabilised.  I'd really like to work at
9600 - is this going to be out of the question?  Are there other patches
that are likely to affect this?  How does the "alternative" tty
driver (from Australia?) measure up on this score?   Has anyone
identified the *real* bottleneck (assuming for a second that it *is*
one thing - rather than a multiplicity of interactions)?

Thanks,
