7: Checksum (Version 1.5, 2.1)
7: Mode Indicator (Version 2.3)
A :
GPS positioning
D : DGPS positioning
N : Not positioning
S : Simulation mode
8: Checksum (Version 2.3)
Note 1. For version 1.5, when not performing positioning, outputs last measured position
data.
For version 2.3, when not performing positioning, outputs last measured position
data, date, and time.
For version 2.3, when power is turned on, or master reset is performed, the initial
time, date, and position settings are NULL.
