[AusNOG] iPhone serial port

[Chris Pollock]

The USB Sync cable won't do - there are only a few pins connected.  You need a fully populated dock connector (or at least, the correct partially populated one which aren't for sale generally).

MAX-232 chips will do fine if you want to do it ghetto, you just need the some capacitors to make them go.

The apple side of things is TTL, yes.
