Had to make a new VP932 adapter

Well, my first attempt at a VP932 adapter revealed some problems so I've ordered a second revision.

This one has a MAX232A chip on the board.  I wasn't able to find a solution without converting to RS232 voltages, even though the AVR on the Dexter board can accept TTL serial natively.  This is partially due to the safeguards I put in place for VP931 (Firefox) support.
