AVR-Chat

A common practice, where a bit of inefficiency is OK, is to send numeric
information larger than a byte is its HEX-ASCII or Decimal-ASCII form,
rather than, say, 4 binary digits. That way, there are no byte-order or bit
order issues for the other end of the link to have a-priori knowledge of.

You decide. The code for the AVR (or any other processor) has
to match the sender's protocol.
