ARF868 Radio Modems - User guide version V1.6
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
