2455 + 5V relays

The PIC just does USB<->relay.  I want to control the relays from Erlang.
What protocol to use?

Binary is easy in Erlang so how to extend the interpreter such that it
supports both dev mode and application messages?  Preferably without

Jumpering the board would make most sense.

Since this is only for debug, why not just run racket?
Alternatively, just send the protocol and save a dictionary of words.

Flow control is simple: read lines until "OK\n"

The remaining problem is to distinguish the ttyACM nodes.
