  13.        <FW5>      2/7/97    ES        Added defs for queueing client Apple Events.
  14.        <FW4>    10/22/96    ES        Added driverRefNum and driverOpened and removed
  15.                                     delayedNotificationRef from AVTDriverData record.
  16.        <FW3>     6/20/96    ES        Made this look more like a .i generated interface.
