Hi
I am in need of some help.
I have a GSM modem which i am trying to use with a SIM card - to allow text messages to be sent to the SIM and then sent via the COMM port to my PC - where I will have an app running which will read on that COMM port.
I have managed to set up most of this but no matter how many times i send a text to the SIM in the GSM modem - i never see a notification of a new SMS incoming - and it never gets routed to the COMM port.
I have been told that there is a way to set up the modem to basically forward any incoming text in the SMS down the COMM port but as i have said i have been unable to do this.
I believe this may be done with the AT+CSMS command but i have had no such luck at present.
For a bit more information, the GSM modem i have doesnt have any internal memory store, so i am guessing I'd need some way of recognising a new incoming message on the SIM and it then being forwarded - as it cant be stored on the ME.

If anyone can help me at all I would really appreciate it.

Take a look at the AT+CNMI command in the GSM 7.05 spec.

If you do AT+CNMI=,2 then most incoming messages will be directly routed to the COMPort.
