Thanks.  I've got serial gdb debugging working on the console
channel, so I'm going to try to split the diag and debug
channels next.

In order to avoid loosing input characters I got rid of the
timeouts in RedBoot's gets(), so now if there's no input on a
UART, it doesn't delay. It checks the next UART (or the
network) immediately.  I don't understand the purpose of the
delay after checking a UART -- my configuration works a lot
better without them.  

Since nobody is calling the 1ms delay routine that updates the
system time, I did have to add to the main loop a call to a new
routine in ticks.c to advance the system by about 80us
everytime through the loop.  The unfortunate thing about that
setup is that you have to tune the "system time adjust" value
by hand to get a reasonably accurate system time.

But, ping resonse time is 1-2 ms and I never loose console
characters at 57.6K baud.  :)
