INTERFACING ARM WITH WAVECOM MODEM

The Wavecom modem (or any other modem, for that matter) neither knows nor cares what is connected to it - the interface works as defined in the modem Manual irrespective of whether you connect it to a PC, an ARM, an 8051, a dumb terminal, or anything else!

So see these threads:

You will also need the Wavecom AT Commands Manual - from Wavecom.

Similarly, as far as serial IO is concerned, the ARM neither knows nor cares what is connected to its UART - so the serial comms part of this no different from any other serial comms project...

You do realise that Wavecom has a specific feature that allows you to run your embedded application within the modem - thus obviating the need for an external microcontroller:
