Hello all, I've been thinking of a few things and was wondering if anyone has any experience with trying to interface a PIC to a Nokia 5190 through it's serial cable? I know that that 5190 (unlike it's 51x0 cousins) does NOT support a standard AT command set on the it's serial port. What I'd like to do is send and receive SMSs using this phone and it's data cable. I'm not really interested in this moment with going with another phone/GSM module simply for cost reasons (I have two 5190s and a serial cable ready to go). Also I don't really care about doing any other data functions, just sending and receiving SMSs. Thanks for any hints.
