I agree that the Stallion is smart, but it is not fast. On our in-house
benchmarks which were the Anvil benchmarks as modified by Specialix,
Anvil came in behind: 1)Equinox 1)Arnet 2)Computone 3)Digiboard.  They
finished behind our Multiport board at speeds less than 38.4 K baud
as far as speed.    Our Multi[port is a dumb board.

Anvil does a much better job of off-loading the host cpu.  They do
real well in those tests.  They also make some good software enhancements
with crocodile and monitor.

ps since know john of specialix reads this, we didn't have one of
his boards to bench, but I suspect it would have done well...
