Hi, im trying to make an SMS control project and im using T65 , it has a datacable , i connected this cable with PC using hyperterminal , and sent AT commands ..etc and everything is ok , but when i take the 3pins TX,RX,GND from the cable and connect it to the microcontroller , i cant communicate to it and couldnt send AT commands and recieve the Response , i think that cable has MAX232 ...any idea ? also i tried to not use the datacable and use TX,RX,GND from the phone itself , i found its really hard to solder it ..
