NOTES:
This message should only be used if it is imperative that the event mark
number be externally controlled, otherwise the $EGEVT message should be
used. If the mark number sent is the same as the current mark number the
message will be ignored.
A shortcut to the Windows HyperTerminal application is provided to check the
navigation input. You must quit the application before running, and may
need to modify the properties if not running at 4800 baud. A sample display
is shown below.

NOTES:
The number of incoming strings should be limited to the five mentioned
above.
For accurate fixes, the navigation strings should be updated once a second
or faster.
