/*
 * This ATI module and the AT commands implemented therein are a FreeCalypso
 * addition.  The purpose of these AT commands is to exercise the audio
 * capabilities of the firmware - by using these commands, you should be
 * able to emit sounds from the speaker or record voice from the microphone
 * without needing to be in a call, and without bringing up GSM at all.
 *
 * Our corrected implementation of the AT@AUL command (originally added
 * by Openmoko) has been moved into this module as well.
