Add .verions to the CLEANFILES+= on those Makefiles that create a version.c
file.
Remove reference to nonexistent file ref_omega.c in one Makefile.
Fix copy of authdes.c.expot so that it works with or without obj directories.
No compiles both with and without obj directories.
can actually write a sane netif device to support one of these. Note that it
was necessary to steal a netisr bit from another protocol; I took the one for
PF_DATAKIT (no great loss).
a binary link-kit. Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.
NB: -Wtraditional will henceforth be forgotten. This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax. These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.
Entries for 800 and 820 fixed.
From vak@kiae.su:
incorporate Joerg Wunsch formatting code
correct handle timeouted operations
fixed entry for 720 media
GAP values changed suitable for possible format code addition.
Read/write GAP always 2 now.
Interleave parameter added for possible format code addition.
Many logical formats added.
720K physical drive added.
Problems: still can't read 720..820 media in 1.44 drive.
800K in HD 5.25in (maximum for DD diskettes)
1.44M in HD 5.25in (for easy distributions)
1.46M in HD 5.25in (maximum for 5.25)
Some cosmetique changes.
Now minor looks like UU DDDDDD, UU - unit, DDDDDD - density.
If density == 0, CMOS-detect format assumed.
For old users/pgms use fake partitions now, i.e.
ln fd0 fd0[a-h]
No new floppy names added (expect fd? and rfd?),
because don't have agreement yet, so make devices
only for CMOS-detected formats.
Now minor looks like UU DDDDDD, UU - unit, DDDDDD - density.
If density == 0, CMOS-detect format assumed.
Fix attach code for correct work with unknown CMOS
floppy types.
Trick diskerr to handle new minor.
1.722M floppy in 1.44M drive popular format added.

b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
