Any comments on "escape sequences" / Syncing etc?.

If things never got lost and Murphy had died they might almost not be
needed :-).
But in real world use you are going to sync in some manner.
Conceivably as "raw" and simple as a single escape sequence that
otherwise lets the sender and receiver decide what to make of what's
on the channel. Possibly packets with known preamble and word count
and checksum/CRC or whatever. Proceeding upwards in complexity until
you arrive at X25 or more (obviously not in the context mentioned
here).
What do you do and why? [ "You" there is notionally Olin, but there
are liable to be a range of preferences and reasons].
