During the power saving condition, before sending any AT command on the serial line, the
DTR line must be set to ON to exit from power saving and it must be waited for the CTS
line to go in ON status.
Until the DTR line is ON, the module will not return in the power saving condition.
Issuing AT+CFUN=4[,0] causes the module to perform either a network deregistration
and a SIM deactivation.
If power saving is enabled, it reduces the power consumption during the idle time, thus
allowing a longer standby time with a given battery capacity.
The power saving function does not affect the network behavior of the module, even
during the power save condition the module remains registered on the network and
reachable for incoming calls or SMS. If a call incomes during the power save, then the
module will wake up and proceed normally with the unsolicited incoming call code.
AT+CFUN?
Read command reports the current setting of <fun> in the format
+CFUN: <fun>
AT+CFUN=?
Test command returns the list of supported values for <fun> and <rst>.
