Serial communication to GSM modem with custom AT commands.


Recommended Posts

Hello all.

I'm aware of the built in functions for sending and receiving SMS via the Cinterion EHS6 modem.

Does anyone have experience with commanding the modem directly with AT commands using COM Rx and COM Tx? 

What I would like to do, is to be able to call the number of the modem. Check the caller ID with the PLC, and have some actions based on the results. 

Based on the AT command reference document, it should be possible.

Would appreciate any feedback on this. Thank you.
