	  The serial character function is a generic function driver that

	  exposes a pair of bulk IN and OUT endpoints which are backed by

	  a character device and mapped to its read/write routines. The

	  function also supports a single interrupt IN endpoint for

	  asynchronous notification to the host. This driver is typically

	  used to support DUN/NMEA functions.
