Is it possible that you can give me some information on how
do go about with the following:

What components do one use to go about for the above design.I would like to use a Nokia phone (61 or 30 series) to do the above interfacing.Is it possible that you can tell me where I can get the AT commands for the Nokia

I would like if you can inform me on the specifications and protocol to use to communicate or control via Short Message Service(SMS) on the cellular phone with a microcontroller.

I would like to control I/O via a cellphone (e.g. switch LEDs or relays via SMS with my cellphone).
Because phone company usually treat SMS packets as VERY VERY LOW PRIORITY.In the worst case, the message may take more than 24 hours to arrive. For the best performance, I would like to make a normal voice call and use DTMF to encode your messages.
Is it possible that you can give me information on the above

I would appreaciate it if you can give me some info and support .

Thanx in advance

Hi All,
   I use Siemens TC35 GSM Module. I have to use this as an modem to dial up an ISP, then connect to an Internet connection & then transmit data to an particular website. These datas are then manipulated using the IIS server.
   Now tell me, How to I dialup an ISP & provide the Username & password & rest other acknowledgements.
   Also is that possible of sending the direct data calls to an other GSM Module & read the datas from them, If so How to do the data calls & how to recive them.
   If using the GPRS can we directly connect to the website(IP address), as soon as the GPRS mopdule is switched ON. If so what are the steps to do so??
   Pls help me with the source code available or with the Hints or steps to be done.
   Its very urgent so pls help me out.
Thanks in advance.
