Set command stores in the internal Real Time Clock an alarm time with respective
settings. It is possible to set up a recurrent alarm for one or more days in the week.
 Currently just one alarm can be set.
 DO NOTE! Alarms are not supported after disconnecting from power. Coin
cell are supported. In case of a power cut, alarm will be deleted and needs to be
re-set.
When the RTC time reaches the alarm time then the alarm starts, the behavior of the
MODULE depends upon the setting <type> and if the device was already ON at the
moment when the alarm time had come.
Parameters:
<time> - current alarm time as quoted string in the same format as defined for
+CCLK command (i.e. "yy/MM/dd,hh:mm:ss±zz"), unless the <recurr> parameter is
used: in this case <time> must not contain a date (i.e."hh:mm:ss±zz")
<n> - index of the alarm
0 - The only value supported is 0.
<type> - alarm behaviour type
0 - reserved for other equipment use.
1 - the MODULE simply wakes up fully operative as if the ON/OFF button had been
pressed. If the device is already ON at the alarm time, then it does nothing.(Default)
2 - 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 issues an unsolicited code every
3s:
+CALA: <text>
Where <text> is the +CALA optional parameter previously set.
The device keeps on sending the unsolicited code every 3s 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. (default)
3 - 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 starts playing the alarm tone on
the selected path for the ringer (see command #SRP).
The device keeps on playing the alarm tone until a #WAKE or #SHDN command is
received or a 90 s time-out occurs. If the device is in "alarm mode" and it does not
receive the #WAKE command within 90s then it shuts down.
If alarm expires during a call alarm sound will stop when the call is disconnected.
4 - 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 brings the alarmpin high,
provided that one has been set (using #ALARMPIN or #GPIO), and keeps it in this
state until a #WAKE or #SHDN command is received or a 90 seconds timer expires. If
