Command Description

The test command returns the supported values of the parameter <atten>.

The read command returns the current attenuation value on the microphone path for the current audio device (selected by AT^SNFS).

•It is not allowed for audio device 1

•As long as the microphone is muted, the write command is temporarily disabled

•Setting of value 0 is not allowed (use AT^SNFM=0 for this).

•For values greater than 32767, 32767 will be used.
