MAX232 Level Converter

[mister_e]

basic of a MAX232... an inverter + level converter (from 5volt to close to 15 volt)

SO, since the computer must read an inverted signal, you must send it inverted... Your pic send it not inverted(true) to the MAX232, the MAX232 invert the signal to the PC... YES you must use T for you communication with a MAX232

Thanks for that. Problem solved.

I really should read manuals before setting out to do these sort of things.

Doahhhh!.
