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:
+ALARM: <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 90s timeout occurs. 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
90s timeout occurs. If the device is in "alarm mode" and it does not receive the #WAKE command
within 90s then it shuts down.
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 pin 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 90s
timeout occurs. 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.
<text> - unsolicited alarm code text string. It has meaning only if <type> is equal to 2 or 5 or 6.

wait for response OK
TIP: Remember that the string time has to be encapsulated in double brackets, furthermore the
Alarm time will not be computed for different timezone, therefore the alarm time will always
refer to the same timezone as the clock setting regardless the timezone set in the +CALA
command.
NOTE: if you use the GPIO6 pin as ALARM OUTPUT, then you MUST set its direction to
"alternate function" (see par. 3.6.2.5) otherwise the pin will not respond to the alarm settings.
In case the alarm mode is equal to 1,3,7 then a dummy empty text shall be inserted "".
NOTE: if you use the unsolicited codes +ALARM: <text>, then you must fix the port speed rate
(see par. 2.5.1) and store it in the active profile (see command &W), in order to make the Telit
GM862-GPS boot with the desired port speed, otherwise at the alarm wakeup, the module will
start with the default port speed that may differ from yours.
