9 AT Command Reference
Notes for entering AT commands
Each AT command starts with the letters AT and ends with a “Carriage Return” (CR).
Capital and small letters will both be accepted, but the leading characters must be either
‘AT’ or ‘at’.
The command line is evaluated after the modem receives a return command.
In the description, a parameter with the letter <n> means that it can have various values.
For example AT&C<n>, where <n> can have the values 0 to 1.
For commands which expect a parameter but don't have a parameter, the modem will
automatically assume the parameter 0. For example, the commands ATI and ATI0 will
have the same effect.
Several commands can be combined to form one single AT command line (Example:
AT&K3&C0#DHCP=1).
Syntax:
<expression> Input of a parameter
<pause> Means a waiting period of one second
[expression] Optional input of a parameter
The factory settings are marked “(default)”.
Individual value query
Most parameters can be read using AT&V (overall view) or per individual value query.
Each parameter that is set with '=' is queried with '?'.
Example: AT#PORT=1234
AT#PORT?
1234
Storing settings permanently
The set of parameters is organized into two different groups. The settings that can be
stored using AT&W are immediately stored in the current profile after having been en-
tered, but will only be stored permanently in the memory with AT&W. (see AT&W)
Example: After ATE0 the echo is immediately switched off. However, after a restart echo
will be available again. ATE0&W will switch the echo off permanently.
All other settings (the so-called network settings) will be immediately written into the
fail-safe memory, but will only be available after a restart.
