Test command
AT+CFUN=?
Response
+CFUN: (list of supported <fun>s), (list of supported <rst>s)
If error is related to ME functionality:
+CME ERROR: <err>
If error is related to ME functionality:
+CME ERROR: <err>
Parameter

Read command
AT+CFUN?
Response
+CFUN: <fun>
If error is related to ME functionality:
+CME ERROR: <err>
If error is related to ME functionality:
+CME ERROR: <err>
Parameter
See below
Write command
AT+CFUN=[<fun>
[,<rst>]]
[,<rst>]]
The write command can be used to reset the ME, to choose one of the SLEEP
mode levels or to return to full functionality. For <fun>=5 or 6 the application
must be configured to use hardware flow control. This is necessary for the CTS
signal level to be transparently transmitted to the TE.

NON-CYCLIC SLEEP mode:
AT+CFUN=0 disconnects immediately any circuit or packet
switched call in progress. The ME goes into power saving
mode. While the NON-CYCLIC SLEEP mode is on, the AT
interface is not accessible. Consequently, once you have
set <fun> level 0, do not send further characters. Otherwise
these characters remain in the input buffer and may delay
the output of an unsolicited result code.
The first wake-up event stops power saving. The ME is
caused to return to full functionality and to stay fully opera-
tional.

Full functionality:
ME operates in IDLE, TALK, DATA, IDLE GPRS or DATA
GPRS mode.
If the ME is in one of the two CYCLIC SLEEP modes you
can issue AT+CFUN=1 to stop power saving and go back to
full functionality. Keep in mind that, unlike the reset
command described below, this action does not restart the
ME but only changes the level of functionality. See
parameter <rst> for details on the reset.

CYCLIC SLEEP mode:
AT+CFUN=5 disconnects any circuit-switched call in prog-
ress, but has no effect on a GPRS call. The ME goes into
the power saving mode 2 seconds after the last character
was transmitted over the serial interface. Sending charac-
ters over the serial interface resets the timer.
The first wake-up event stops power saving. Also, you can
enter AT+CFUN=1 to terminate power saving.
