Ultrix TK50 driver problem

[Hurf Sheldon]

with a reel drive. It compiles & runs without error but restore  t
shows only the last filesystem  dumped on the cartridge. It appears
that a close() to the tk50 is also issuing a rewind. Hints on a  fix
would be appreciated. 
	We have sources  but it isn't obvious to me where to look  first.
Thanks in advance.
