AT+CFUN Set phone functionality

This command serves to control the functionality level of the ME. It can be used to reset the ME, to choose one
of the SLEEP modes or to return to full functionality.
Intended for power saving, SLEEP mode reduces the functionality of the ME to a minimum and thus minimizes
the current consumption. SLEEP mode falls in two categories: NON-CYCLIC SLEEP mode
CYCLIC SLEEP modes, selectable as
NON-CYCLIC SLEEP mode permanently blocks the serial interface. The CYCLIC SLEEP mode, however, is a
dynamic process which alternatingly enables and disables the serial interface. The major benefit of all CYCLIC
SLEEP modes is that the serial interface remains accessible and that, in intermittent wake-up periods, characters
can be sent or received without terminating the selected mode. The best choice is using
these modes TC35i automatically resumes power saving, after you have sent or received a short message or
made a call. =5 or 6 do not offer this feature to the same extent and are only supported for compatibility

with earlier releases. In all CYCLIC SLEEP modes, you can enter
take it back to full functionality. Please refer to section
ways of waking up the module.
For CYCLIC SLEEP mode (
ware flow control. This is necessary since the CTS signal is set/reset every time when the ME listens to a paging
message from the base station. This is the way how the module indicates to the application when the UART is
active. For detailed information on the timing of the CTS signal refer to [2]. The default setting of hardware flow
control is 0 which must be altered to
