A.8.119 +PG – GPS: GPS Automatically Sent
Exec Command: +PG=<CD level>[,<mode>[,<rate>[,<messages>]]]
This command automatically sets the unit to return GPS information at a set rate.
<CD level>
CD level controlling when GPS information is sent. 0 is off, 1 send when CD
is low, 2 send when CD is high, 3 send when CD is low or high.
<mode>
For the initial version this does not do anything. In future versions this will
determine whether to send in regular mode or in tracking mode. 1 is in
regular mode only, 2 is in tracking mode only and 3 is in regular or
tracking mode.
<rate>
Frequency that the GPS information is sent over in seconds.
