+CALA - Alarm Management
GPIO6 high, provided its <direction> has been set to alarm output, and keeps it
in this state until a #WAKE or #SHDN command is received or a 90 seconds
timer expires. If the device is in "alarm mode" and it does not receive the
#WAKE command within 90s then it shuts down.
5 - the MODULE will make both the actions as for type=2 and <type>=3.
6 - the MODULE will make both the actions as for type=2 and <type>=4.
7 - the MODULE will make both the actions as for type=3 and <type>=4.
8 - the MODULE wakes up in "alarm mode" if at the alarm time it was off,
otherwise it remains fully operative. In both cases the MODULE sets High the
RI output pin. The RI output pin remains High until next #WAKE issue or
until a 90s timer expires. If the device is in "alarm mode" and it does not receive
the #WAKE command within 90s. After that it shuts down.
<text> - unsolicited alarm code text string. It has meaning only if <type> is equal
to 2 or 5 or 6.
<recurr> - string type value indicating day of week for the alarm in one of the
following formats:
“<1..7>[,<1..7>[, … ]]” - it sets a recurrent alarm for one or more days in the
week; the digits 1 to 7 corresponds to the days in the week (Monday is 1).
“0” - it sets a recurrent alarm for all days in the week.
<silent> - integer type indicating if the alarm is silent or not.
0 - the alarm will not be silent;
1 - the alarm will be silent.
Note: a special form of the Set command, +CALA=””, deletes an alarm in the ME
Note: The "alarm mode" is indicated by hardware pin CTS to the ON status and
DSR to the OFF status, while the "power saving" status is indicated by a CTS -
OFF ,DSR - OFF and USB_VBUS – OFF status. The normal operating status is
indicated by DSR – ON or USB_VBUS – ON status.
During the "alarm mode" the device will not make any network scan and will not
register to any network and therefore is not able to dial or receive any call or SMS,
the only commands that can be issued to the MODULE in this state are the #WAKE
and #SHDN, every other command must not be issued during this state.

Read command returns the list of current active alarm settings in the ME, in the
format:

AT+CALA=?
Test command returns the list of supported index values (currently just 0), alarm
types, maximum length of the text to be displayed, maximum length of <recurr>
and supported <silent>s, in the format:
+CALA: (list of supported <n>s),(list of supported <type>s),<tlength>,
