I notice that while I have a normal dearth (man 7 mt (:-))
of information on the /dev/mt devices, the new 8mm drives
are as yet undocumented.
So, we have in /dev/mt, the following:
crw-rw-rw- 5 root 22, 64 Jul 20 16:13 hc0
crw-rw-rw- 5 root 22, 64 Jul 20 16:13 hc0d4
crw-rw-rw- 5 root 22, 65 Jul 20 15:57 hc0d4n
crw-rw-rw- 5 root 22, 65 Jul 20 15:57 hc4
Note, please, that none of these have minor devices 0 (normal)
or 4 (norewind).
I'll happily guess, but a hint from someone who knows wouldn't
hurt. I'll even donate a man page if someone can give me the
real skinney on it, or tell me which FM to dive into.

I'm answering this from home, so I don't have the poop in front of me, but I believe that so far the info is only in the 4.00 release notes. As you probably would have guessed, hc0/hc0d4 are rewinding, hc4/hc0d4n are non-rewinding. The minor numbers are what they are because major# 22 is the general SCSI driver for the M/2000, and the device numbers correspond to a multiple of the target ID. -- ROGER B.A. KLORESE MIPS Computer Systems, Inc. phone: +1 408 720-2939 928 E.

I lied, of course... this stuff did not make it in to the release notes. I'll see to it that it is in manual updates. -- ROGER B.A. KLORESE MIPS Computer Systems, Inc. phone: +1 408 720-2939 928 E.
