Yes, I am in the process of using a serial cable to transfer 386BSD
files (bins) from my 486/ESIX-3.2 to my 386/25 running the bare 386BSD
binaries.  I've been seeing LOTS of "com1: silo overflow" message
(even though I'm using COM2 (!)), and some "Retry 0: Bad escape 
sequence 20" and "Retry 0: Garbled data subpacket" messages.  I'm using
zmodem.  It does seem to be transferring the files, although I'm sure
the rate is low due to the excessive errors.

I do not have an NS16550 UART on the serial port, and am running at 
9600 baud, so maybe that's the problem.  Also, stty doesn't seem to
accept anything higher than 9600.
