  Low-level MSCP access to HSJ Jukebox? 
 The Question is:
 
I have been searching around in the I/O User's Guide and other places for
 documentation on the functions used to control robotics connected to some type
 of DSA controller like the HSJ.  I believe that MRU uses DUDRIVER to control
 robots connected in that
manner.  Can you direct me to the documentation?  Also, will this be the
 approach with FibreChannel attached robotics?
 
 The Answer is:
 
  These command and control sequences are usually specific to the particular
  widget -- the contents of the OpenVMS I/O User's Reference Manual involve
  devices that have generic support in OpenVMS.  You will need to look at the
  particular controller(s) and juke-boxes involved in great detail -- in some
  cases, the I/O widgets will present themselves as a DU-class disk device,
  even though the device itself is the control interface and NOT a disk.
