Sending SMS with Nokia 6210 using PICF819

[skimask]

I am trying to send SMS messages from a Nokia 6210 mobile using a PICF819. I have a Nokia DLR-3 data cable which I can connect to HyperTerminal and send SMS messages using AT commands.

Search the GSM section of the forums...

How can I use the PIC to send the AT commands instead of HyperTerminal? I think the data cable needs RS232 so I was going to us a MAX232 between the PIC and cable but I am not sure what pins to connect.

SEROUT/SEROUT2/HSEROUT, hardware serial module of a PIC, bit bang an I/O pin set to output mode. Lots of options...one manual to read...
