Hi, Can someone please tell me how the AT commands sent to the cellular processor from the hyperterminal are sent utilsing the serial com port that is what is the format of the data packets n stuff i.e from electronics point of view.I would be also thakful if u could give me links where i can find such info Thanking you in Advance in anticipation

I hve successfully executed AT Commands like making a call and stuff but was unable to recieve calls or sendin and recieving SMS using AT Commands . So please help me out coz its real urgent .Is there anyone working on the same and how far have u reached.

:'( Are u sure there are no AT commands for seding or recieving SMS through PC and another clarification is it possible to use the AT command of Nokia or GSM for that matter for this i.e.LG RD2030. Thanking u in anticipation.
