Example of a series of commands and corresponding replies as one could see them on a terminal:
Syntax of the Command

ATS200=9
ATS200=527
ATS231=0
ATS200 ?
ATS231 ?
AT&W
ATO
Interpretation of the above example: the user wished to save a new radio configuration (channel 527, power 27dBm) after having made a
parameter error (reply E) and an unauthorised configuration request (reply W). The modem allows neither the saving of this invalid configuration
nor the use of the product in the communication mode.
5.3. Description of registers
When switching on the ARF868 modem operates according to the last configuration saved (factory configuration if its the first switching on, or
if this configuration has not been changed).
Modification commands, type ATS<n>=<m> or ATR allow the content of registers to be modified. The product is usable with each new
configuration as long as it is not disconnected.
On the other hand the modified values will be applied next time the modem is switched on only if they have been saved AT&W command
