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.
