//   are as follows:
//	Zero:     indicates a user waypoint ("subclass" is ignored).
//	Non-zero: indicates a non-user waypoint ("subclass" must be valid).
//
//  For non-user waypoints (such as a city in the GPS map database), the
//	GPS will provide a non-zero value in the "class" member, and the
//	"subclass" member will contain valid data to further identify
//	the non-user waypoint.  If the Host wishes to transfer this
//	waypoint back to the GPS (as part of a route), the Host must
//	leave the "class" and "subclass" members unmodified.
//
//	For user waypoints, the Host must ensure that the "class" member
//	is zero, but the "subclass" member will be ignored and should be
//	set to zero.
//	
//	The "lnk_ident" member provides a string that indicates the name
//	of the path from this waypoint to the next waypoint in the
//	route.
//	
//	For example, "HIGHWAY 101" might be placed in "lnk_ident" to
//	show that the path from this waypoint to the next waypoint is
//	along Highway 101.  The "lnk_ident" string may be empty (i.e.,
//	no characters other than the null terminator), which indicates
//	that no particular path is specified.
