Overview AT Commands INSYS WLAN serial 2.1
15 Overview 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.
Example
AT&D<n>
, where ‘
n
’ can have the values 0 to 3, for example
AT&D2
(DTR set-
ting). For commands which expect a parameter, but are specified without one, the mo-
dem automatically assumes the parameter 0. This means that, for example, the com-
mand
ATZ
equals the command
ATZ0
.
Syntax:

Input of a parameter
