[Noisebridge-discuss] G1 serial interface incantation

[Michael Shiloh]

this i have no idea. i'm more of an openmoko person than a g1 person.

i'm not ioerror, by the way.

one thing i do know: you need 3 wires for serial. you need ground, as i 
discovered years ago with a modem and an old-school terminal.
