I have been working on sim900d a lot and its communication with pc and micro-controllers. I have a NOKIA 5130 XPRESS MUSIC cell phone.. I want to connect it to my PC using its data cable and check the AT-COMMANDS.. I connected the phone using data cable and 9600 baud but at-commands not working.. how would i check it for at-commands? besides what would be the baud rate of my phone? Thanks in advance
