Hi microkam,

I can't answer that since I've never used any of these phones, but I'll bet some of the folks posting in that particular thread can answer whatever questions you have.

microkam,

PLEASE STOP SENDING PM's

I do't know the specs every single nokia model.
The easiest way would be to get a datacable with the phone.
(you would need the connector anyway)

With a MAX232 type of inverter/level-shifter
at the PIC end there shouldn't be a problem to connect.
