Tar Tape problems

[Richard M Emberson Jr]

I've got a 386 AT clone, ISC2.2, and an Archive drive. After reading four
or five tape (tar -xfv /dev/rmt0) the next attempt to read a tape hangs.
I can kill the process but the device remains busy. The only way I
have found to clear the busy device is to powerdown to the reboot state.

Is there a way to fix this?? Can I unbusy the device?
