The Export Media Message is used to notify the requester that Export Media
Command successfully completed or that an error occurred causing the command to
fail. With an Export Command, it will return the CAP position the tape label was
moved to (0-13 top to bottom) and the slot position the tape label was moved from.
The first byte of the label field will have a V, which stands for export update. A –1 (a
255 will be in both bytes) means that no change occurred. The structure of the Export
