 How do I get the tape off-line or unloaded or write locked?
 The idea is that operator intervention should be required before
 more writes can occur to a given cassette. (E.g., when running backup
 I want to be able to force the operator to mount another tape, not
 just say he did.  I can't quite do this with mt, but at least I
 can do an mt offline or mt unload to force him to go over to the
 drive and do something.  tctl doesn't have offline, unload, writelock,
 etc.)
