SLIP vs. prefix coding

Prefix coding (sending the size of the message first) makes the code
simpler, but has a problem when it comes to recovering due to
communication errors.  Once sync is lost it likely won't recover.

SLIP can help with this.  It automatically resynchronizes producing
bad but segmented frames.  Adding error detection can filter out the
bad packets.
