NMEA Configuration commands

The following NMEA-like input sentences can be used to configure the Vector 3D.

To query what is the current value of most parameters, leave off the last ",value" portion of the sentence.

For those sentences that enable the output of repeating NMEA data sentences, the range of valid repeat rates is shown in
parentheses; "0" causes the sentence to be disabled. Some sentences may only be disabled or enabled - with a NO or
YES parameter value.
