+CFUN: (list of supported <fun>s), (list of supported <rst>s)
If error is related to ME functionality:

Execute command
AT+CFUN=[<fun
>[,<rst>]]
Response
OK
If error is related to ME functionality:
+CME ERROR: <err>
Parameter
<fun> 0 Minimum functionality (Sleep mode)
Note: If command AT+CFUN=0 is input, do not send further
characters until the device really has entered sleep mode.
Otherwise these characters remain in the input buffer and will
delay output of an URC (see pg. 137, e.g. “RING”).
Note: Any established connection will be terminated.
1 Full functionality (only used as placeholder for +CFUN=1,1).
<rst> 0 Do not reset the ME before setting it to <fun> power level.
(only used as placeholder for +CFUN=0,0).
1 ME resets and restarts in full functionality mode. If <rst> = 1
the first parameter <fun> has no effect.

Note
1. For indication of current ME´s operation mode see „AT^SSYNC Configure
SYNC Pin“, pg. 132.
2. Identify a ME´s standby mode can be done via it´s lowered supply current
only. The time power saving can start after command issue is unspecified
due to remaining network activities.
3. After restart it is necessary to use AT+CPIN again.
4. GSM module wakes up with incoming call, Real Time Clock alarm, falling
edge of RTS (RS-232 levels) and with the appearance of an unsolicited result
code (URC, see chapter 7.3).
