When I evaluated ANVIL Stallion boards back in January (2.1.3 or 2.1.7 drivers)
I had input problems at 9600 and 19.2 baud also.  The simple protocol I was
using was a send/wait much like Xmodem.  When I reduced the input packet size
to 384 bytes from 1024 input worked fine at 9600 baud from multiple inputs.  I
would venture that if you told zmodem to use smaller packets, it would work.
This is not to say that their drivers shouldn't have handled the larger packet
size -- or that they should have admitted the limits up front!

Note that the benchmarks are always in 'cooked' mode -- how much emacs or vi
editing do YOU do in 'cooked' mode?
