Things yet to be done
=====================

Rewrite local command handling:

  (1) need to handle ranges, e.g.

      /drop 1 3-4 failed

  (2) centralized argument (count) checking?

GUI?

Need to find out more about:

  (1) format of outgoing packet header
  (2) output of various commands (qamstat, qpsk status, etc)
  (3) what the 'shell' command does
  (4) how to use the eeconfig commands (wfile, wimage, rimage, etc...)
