4.10. Real-Time Clock Commands
4.10.1. $RTCALRM Real Time Clock Alarm
Command Function This command handles the setting and
querying of the RTC alarm registers.
When the alarm feature has been enabled
the $EVENT engine will be invoked upon
the going off. If the $RTCWAKE call is
invoked following the alarm feature setup
the modem will power back up
automatically upon the alarm going off. The
actions of these two features are mutually
exclusive of each other, so one or the other
will occur but not both.
