aci3 vocoder control revamped, AT@VSEL now works as it should The vocoder control code (hl_audio_drv.c) that came with the TCS3 version of ACI was totally broken in the Calypso config (VOCODER_FUNC_INTERFACE) and worked in the standard analog voice environment only by luck. This code has now been rewritten to work correctly with our Calypso platform and TCS211 L1, and our new AT@VSEL mechanism (automatic enabling and disabling of MCSI voice path as the modem enters and exits the voice call state) now also works as designed.

/*
 * 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.
