Can anyone explain me the basic concept or provide me any documentation on sending receiving the sms using the gsm modem connected to pc via a C# application.
I did find lot of source codes but not able to get what is the procedure or algorithm behind it.
One such link is here
http://www.freestudentprojects.com/c-net-projects/send-and-receive-sms-in-net-using-gprs-modem/
I downloaded the source code but the things are not quite clear.
thanks,

You need ATCommands to communicate with GSM modem. This is very good codeproject article for understanding the procedure with demo.
