I've modified my version of RedBoot to poll the serial-ports
and ethernet interfaces continuously instead of sleeping
between polls.  If you'd like, I could summarize the changes
involved (they're not extensive).  It improved both network and
serial-port performance dramatically.

My version still ignores the network when in the "middle" of a
serial-port-received command line.  That wouldn't be hard to
change either, but in my application it doesn't do any harm.
