Thanks guys for your responses. After doing some reading I realised that the phone I intend to use DOES support a serial conection but I'm not exactly sure how to connect it.
It's a Moto V400 and here are the pinouts..
Mobile phone
interface pin Description
1 GND
2 R=25 or 33 KOhm to GND in data or charge cable
3 +6v charge voltage
4 Tx
5 Rx
6 RTS
7 Vbus (connect to pin 3 if not used as IC power)
8 CTS
9 DCD
10 RE
11 DTR
12 DSR
13 Serial Enable (if this pin is not pulled to ground your serial cable will not work)
I connected pins 4 and 5 to my PIC's UART and connected all the GND connection but nothing. Do I need to connect the other pins ?
