Have you tried connecting to a PC with a terminal program like the one in Micro Code Studio?

Camola, I am a little confuse. I did a bit of research on google and it seems that
nokia 6210 has a USB connection. Are you sure your phone has a serial connection?

Then try SERIN2 in inverted mode for a test. Could be an external hardware problem?

Camola, from your code it seems that you are using portC.6 and PortC.7 for communication with cellphone. If this is correct then:

Connect pic portC.6 to max232 pin 11 (TTL Tx)
Connect pic portC.7 to max232 pin 12 (TTL Rx)
Connect max232 pin 14 to phone serial cable pin 3 (Should be Rx ?)
Connect max232 pin 13 to phone serial cable pin 2 (should be Tx ?)
Connect circuit ground to phone serial cable pin 5

(If you connect it to the PC I assume you have a 9 pins DB female connector)

It should work. If it doesn't invert connections at the serial cable pins 2 & 3

Hi,

Yes it have and there are nokia cables to conect it to pc rs232 i have one from nokia and works fine with hyperterminal.

Did you powered the cable working with hyperterminal? If not you don't need to do it with max232.
