S91 10
Data Transmit Level: This S-register sets the modem’s transmit level for the data
mode. This value is stored in the NVRAM but is not displayed by the &Vn command.
The reset commands &F and Zn have no effect on S91.
Since the function of S91 relates to modem hardware, this command should only be
used by the modem manufacturer and never used by a software developer or end
user.
In some countries, the end user is not allowed to change the transmit level. In these
countries, the country PTT checks to make sure that the end user can not change
the transmit level.
Range: 0 to 15 (-15 dBm)
Default: 10* (-10 dBm)
S92 10
Fax Transmit Level: This S-register sets the modem’s transmit level for the fax
mode. This value is stored in the NVRAM but is not displayed by the &V command.

Since the function of S92 relates to modem hardware, this command should only be
used by the modem manufacturer and never used by a software developer or end
user.
In some countries, the end user is not allowed to change the transmit level. In these
countries, the country PTT checks to make sure that the end user can not change
the transmit level.
