But I dont have any idea about it. so please guide me what kind of GSM Interface support for my Requirements and in feature may extend Requirements. what kind of programming language will be simple for write an pc interface to access that GSM interface device.

    You can use something like this https://www.sparkfun.com/products/9533 with https://www.sparkfun.com/products/9427. It will connect to PC over USB as a (virtual) serial port.

    Using system.io.serialport returns array of com ports but how can i identity my usb device's virual port COM. Is there any way to identity a specific usb device virtual port COM address in c#

    Not really. That's one of the limitations of an extremely simple system like serial ports. You'll have to let the user choose a port.

    There is more then 10 COM ports are return by the serialport so its very difficult to choose the correct com port of their device.. can find the exact com port in any other language?

    Really? I have never seen a system with 3-4 serial ports.

    If you use C/C++ you can use FTDI's library to access FTDI devices, which may give you more information, but I'm not sure about that.

    Yes... system.io.serialport returns both physical com port and virtual com port.

    Thank you...!!
