 *
 * Modification History:
 *
 * 18-Jun-87  rafiey (Ali Rafieymehr)
 *	Added QIOWCURSOR ioctl definition. This ioctl is used only by
 *	VAXstar monochrome.
 *
 * 14-May-87  -- fred (Fred Canter)
 *	Added QD_KERN_UNLOOP ioctl definition. This is a duplicate of
 *	QIOKERNUNLOOP, but is needed!
 *
 * 19-Mar-87  fred (Fred Canter)
 *	Changes some ioctl numbers to be consistent with smioctl.h.
 *
 * 08-Jan-87  rafiey (Ali Rafieymehr)
 *	Added two new ioctls to turn the video on and off. These two
 *	are to be used for save screen.
