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.
