5.6. Additional Personal-Locator Related Commands
The following commands are unique to the –PL version of the RV-M7. When you
execute any of these commands, the new parameter is automatically stored in
EEPROM. Unlike the Modem Commands in the table above, you do not need to
issue the “ATSV” command to save –PL related parameters listed in the table
below. The parameters in all GPS commands listed below are automatically saved
to EEPROM when they are executed.
