This doesn't really belong in the Projects category, but I don't know where else to put it.

Function Connection
+3.3 C99, side closest to R59
GND C99, side closest to center of board
TXD (TTL -> RS-232) Pin 13 on MAX3224
RXD (RS-232 -> TTL) Pin 15 on MAX3224
CTS (RS-232 -> TTL) Pin 10 on MAX3224

Pins 19 & 20 need to be shorted together on the MAX3224 (datasheet) to disable auto-shutoff. After soldering 30 gauge wire-wrap wire to the pins, a dab of epoxy on each wire will keep them from breaking.
