    I need help interfacing with a tape drive.  The problem is that
after I written a file to tape, I need to write a number of
End-of-tape marks, after which, I have to backup over the tape marks
so we are ready to write the next file (if needed).

    The problem is that I am tring to do this on VAX running
Unix System V (not BSD or Ultrix).  The tape drive is a TU81.  The tape
driver does not support MTIOC calls.  I would also like to make it general
enought so that it should work with any tape drive on a VAX system.
