"ListenPorts" sub-tag:
This tag specifies the ports on which the device communication server will listen for incoming connections from
remote devices. The attribute "tcpPort" specifies the port on which a TCP listener will be started. The attribute
"udpPort" specified the port on which a UDP listener will be started. If either "tcpPort" or "udpPort" is blank, or
not specified, the the corresponding "listener" will not be started.
"Properties" sub-tag:
This tag includes "Property" sub-tags which specify runtime properties which can be used to further specify the
behavior of the device communication server at runtime. The standard properties that most device communication
server recognize are as follows:
minimumSpeedKPH : (Double) This property specifies the minimum acceptable GPS-based speed. A speed
value beow the value specified by this property will be considered a speed of '0'. This is used to mitigate GPS
speed values which can indicate motion, even when the GPS receiver is stationary.
estimateOdometer : (Boolean) This property specifies the whether a GPS-based odometer value should be
automatically calculated from the valid GPS locations reported by the incoming event. The odometer value of the
current event is calculated by determining the distance from the previous event location to the current event
location, then adding this distance to the previous odometer value.
simulateGeozones : (Boolean) This property specifies whether incoming events should be checked for
Geozone arrive/depart occurances. If the current event was found to have arrive, or have departed, from a
Geozone (as listed in the Geozone table), then the appropriate event, with the arrive/depart status code, will be
generated and inserted into the EventData table.
Specific device communication servers may also support other property specifications.
