The invokeOemRilRequestRaw() and invokeOemRilRequestStrings() methods which have implementations in a number of classes (RIL, PhoneProxy, PhoneBase, and some others) are what you need, but they are not available through the SDK and thus off-limits to us mere mortals.

  1. There is a great review of this in the XDA forum thread:

    How to talk to the Modem with AT commands.

    That thread show you how to send AT commands (ATC) with a remote terminal (USB connected to you PC), but it has not yet solved the problem of how to use a local (phone) terminal to talk to the phone Modem.

  2. You need a terminal application/program to do any talking to the modem (remember, its a 2-way communication). So that's why you need a rooted device, since the root kit usually come with Busybox (that includes a microcom terminal program). Otherwise you have to write your own program.

  3. AFAIK. You can disconnect incoming calls in many other and easier ways than with AT commands.

Use syntax like this and let me know:

echo -e "AT+CFUN=?\r\n" > /dev/ttyUSB0
