These general-purpose counters have no predefined meaning, and they have no
effect on the rest of the system.
Ticks
This counter increments every 1/1200 second, and counts from 0 to 1199.
TX Counter
Seconds elapsed since the last automatic transmission.
Second
This counter indicates the second of the current hour (synchronized to GPS time)
from 0 to 3599.
Pulse Count
This counter is used by the event counter function described elsewhere in this
manual.
Last Digi
Seconds elapsed since the tracker last heard one of its own packets repeated by a
digipeater.
Last Fix
Seconds elapsed since the last valid GPS position fix was received.
Altitude
Current altitude reported by the GPS receiver. Units are 2.56 meters, and 0
indicates an altitude of -10,000 meters. Thus, a value of 5097 is approximately
10,000 feet or 3,048 meters ((3,048 meters + 10,000) / 2.56 = 5096.875).
Result
Return value of the last command line command executed.
