Description:
Use the !TXG command to amplify the microphone output of an analog telephone
device connected to AUX port. AT!TXG0 selects no amplification, AT!TXG4 selects
the highest amplification, and intermediate numbers select intermediate amplification.
CAUTION: Do not adjust the gain unless absolutely necessary. It is very large at
non-zero levels. Adjust only for special equipment that provides very low-level
signals to the analog port.
