Information Please

Hello.
How are you?
I'm new to the forum and would like some information please.
I am thinking of setting up a project using remote access with Arduino 2009 + Arduino GSM Shield (BlueVia).
My question is: Its possible open page internet in Windows XP through a C# program on USB Port PC connected the Arduino + Arduino GSM Shield?

Thanks.

The Arduino communicates with the PC as a serial device.

Anything on the PC that communicate with serial devices, can communicate with an Arduino.

Uhmmm, you can try to read the com port which the arduino is connected to. You can pretty much make a condition saying, if I receive this text message than send some data using serial. Your c# program would read that data from the com port and try to do something after checking it.
