Sending AT Commands to a modem

[tawanda diza]

Hie Team,

I am currently develeping an application for windows mobile. I am using C#2008 for this.
I am sending and receiving messages to and from a server via GPRS.

At the moment i am using the

Socket Connect()

'

ReceiveMsg(Socket socket, byte[] buffer, int offset, int size,int receiveTimeout)

and

SendMsg(Socket socket, byte[] buffer, int offset, int size,int  sendTimeout)

Could someone help me on how to send AT commands directly to the modem to connect, Send And Receive messages via GPRS and not connecting using the above methods,



Thanks in Advance
