18.8 AT^SAIC Audio Interface Configuration

AT^SAIC configures the interface connections of the active audio mode. The write command is usable in audio

modes 2 to 6 only.

If AT^SNFS=1, any attempt to use AT^SAIC write command is rejected with error response. This is because all

default parameters in audio mode 1 are determined for type approval and are not adjustable.

To allocate a specific audio mode to one of the audio interfaces, first select the audio mode with AT^SNFS and

then choose the interface using AT^SAIC.
