I havent done this for a while...
There are some ways to communicate withe a Modem (like the UMTS Modem in the N900) via several comands. I think it was called AT Instruction set. Couldnt find much about it, though.
Anyone already done this?
Does someone have a page for the AT Comands in general and / or the N900 specifically?
Is this even the way you do this on the N900?
