[net.unix] Problems with our tape drive

boyce@daemen.UUCP (Buck Wheat) (04/25/85)

	We have a 750 running 4.2 with one UNIBUS adapter, one CDC hard
disk, and one Kennedy tape drive.  It is configured to the 'tm' interface
and is defined as 'te0'.  A lot of times we get a 'te0: lost interrupt'
when doing 'mt fsf' and the tape continues to spin till the end.
	Does anyone know why we are having this problem or better yet does
anyone know how to correct it.
	Thanks ahead of time.

The tm(4) device handler thinks that any tape operation that takes
more than a small number of seconds (5 from my memory) is a mistake.
If you have a moderate-sized file and a suitably slow tape drive,
it will take more than 5 seconds to skip it.  You either have to skip
files by reading an infinite number of records, or else you have to
hack at the handler.
