QUERY_METERS
This message is sent by the server to request the current state of the runtime
meters (See SET_EXT2_APP_CONFIG for runtime meter setup instructions).
The meters can also be individually cleared via this message. TrimTrac ProE
responds by sending a RESP_METERS (page 178) message.

Table 72, QUERY_METERS Message
QUERY_POSITION
This message is used to command the TrimTrac ProE to report either its current or
its most recently logged position depending upon how the Position Query Mode is
set in the QUERY_POSITION message as shown in Figure 34 on page165.
More specifically, the unit will compute and report a NEW position fix when
queried if and only if the Position Query Mode is set:
1. “P=Compute New Position Fix”, OR
2. “S=Compute if Position Aged” AND there has been motion since the
device last exited the FIX State (i.e. Position Age has become set
“1=Aged”).
If either of the foregoing settings and conditions are true and the device was able
to compute a new position fix as requested, then the unit will respond to the
QUERY_POSITION message by computing a new position fix and sending it in a
new REPORT_POS message (with TriggerType set to “3=Query”).
If the TrimTrac ProE was unable to compute a new position fix prior to
expiration of the GPS Fix Timeout specified in the QUERY_POSITION message,
then a new STATUS_MSG will be sent in response. This new STATUS_MSG
will have the TriggerType set “3=Query”, GPS Status Code set to some value
other than "0=3D Fix, 1=2D Fix or 7=No Fix Attempted" and the Position Age
flag will be set “1=Aged”. No other position information will be provided with
the response.
If either of the foregoing settings and conditions are true, or if Position Query
Mode is set “L=Status Report with Last Logged Position”, the unit will send a
