STE Command
Use the
-STE=
n
command to enable/disable Line-In-Use
and Extension Pickup options. Use
value of
n
for this command in your installation scenario.
If the line is in use and the modem issues an
ATDT
command to dial out, the modem will not go off hook
and will display a
LINE-IN-USE
result code. If the
modem is off hook and the extension is picked up, the
modem will drop the connection.
AT+MS Select/Force Modulation
Command
This command is useful if you need to force the modem
to specific modulations or line speeds.
+MS Modulation Selection
This extended format compound parameter controls the
manner of operation of modulation capabilities in the
modem in one command. See
for valid entries.
Below is an example of how to read the current settings
using the
AT+MS?
command.
=>
AT+MS? <Enter>
+MS: V90,1,300,33600,300,5600
%Q
Line signal quality
Reports line signal quality (DAA-dependent). Returns higher order byte of the EQM value. Based on EQM value,
retrain or fallback/fall forward may be initiated if enabled by %E1 or %E2.
