I want to program GSM mobile. GSM mobile will be connected to a PC via a serial port or usb cable or bluetooth etc. I will send commands from my PC and that command will operate the mobile like sending sms, calling numbers, etc. For this type of programming what libraries should I refer ??? Currently I am referring Asio for socket and threading. What else I need to refer ? Currently I am in analysis stage.
