Group “AT SYS”: Output Format, Factory Default
Settings
AT commands starting with “AT SYS” are used to configure the AT command
interface, to reset the WSA to the factory default settings and to query or save a
user-defined character string.
9.13.1
AT SYS CFG CLEAR
The
AT SYS CFG CLEAR
command resets the WSA to the factory default
settings (see section “Function Description”> … >“Factory Default Settings”).
Restart the device to apply the settings!
Restart the WSA if you have executed the
AT SYS CFG CLEAR
command, as
some settings are not applied until the adapter is restarted.
9.13.2
AT SYS ECHO
The command queries (
AT SYS ECHO ?
) or determines
(
AT SYS ECHO = <x>
) if characters received on the AT command interface
are echoed (
x = “1”
) or not (
x = “0”
).
Only use “AT SYS ECHO” for manual command input!
Only use the
AT SYS ECHO
command in conjunction with manual operation of
the AT command interface (e.g. for keyboard input some terminal programs).
Otherwise, output of the echo can be aborted by output of the response especially
for longer AT commands.
Note on the use of terminal programs
In some terminal programs, the characters entered in the prompt line are not
displayed.
To simplify entering of AT commands in such a case you can configure the WSA
using an AT command (
AT SYS ECHO = 1
) such that it reflects, or “echoes”
the input.
9.13.3
AT SYS HELP
The
AT SYS HELP
command lists the syntax of all AT commands starting with
AT SYS
.
