Virtual Trip Odometer
The $TODOM command records how far the vehicle has traveled. This is
identical to the $ODOMETER feature, but allows the user to reset this trip
odometer without resetting the other odometer.
AT$TODOM=?
$TODOM:(0-4000000000)
OK
AT$TODOM=1234 (where 1234 is distance in meters)
OK
AT$TODOM?
$TODOM: xxxx (xxxx=distance traveled in meters)

The user is able to set a seed value for the Trip Odometer starting at 0 but not
higher than the maximum value of 4000000000.
The AT&F command will not reset the odometer value to 0. (see example below)
The Trip Odometer reading would be a 4-byte value starting from 0 to
4000000000 (maximum of approximately 2500000 miles before it rolls over to
0)
The unit for Trip Odometer shall be in meters.
The Trip Odometer history shall be updated every second.
The Trip Odometer history shall be saved once a minute in modem's memory.
This value shall be retained through an internal or external reset and can be read
upon the next power up or during run time mode. The delta distance traveled
between the minute marks could be lost due to an unexpected reset. However,
the total distance traveled till the prior minute would still be preserved.
The $ODOMETER value can trigger the event engine via input event 70. The
$TODOM value can trigger the event engine via input event 91.
Reset Trip Odometer to 0:
$TODOM=0
