file anymore after this. My link makes it too painful to make
interactive mods, and I don't have the CVS tree here so making changes
for "previous history" have to get done on freefall, with the corresponding
degree of pain.

|Subject: A little problem with MAKEDEV
|
|For a while now, MAKEDEV's been kinda neat: you create the cua* files,
|and it deletes the tty* files; you create the tty* files and it
|deletes the corresponding cua* files. K00l! :-)
[Ed Note - I think this behavior was wrong, and this fix better].
created by Amancio Hasty (specificly, this, in conjunction with his sound
driver mods for dual-mode DMA will allow VAT compiled for BSD/386 1.1 to
run under FreeBSD 2.x.)
be installed on, so they should be in /dev as well.
Removed the smoking remains of dcf*. I didn't realize that it had made it
into MAKEDEV. Gone from cdevsw long time ago, gone from /dev now.
actually have a printer connected or online:
- MAKEDEV: remove all signs of lpa
add lpctl? devices (minor # = unit + 128)
- usr.sbin/Makefile add lptcontrol
- sys/i386/isa/lpt.c implement the LP_BYPASS flag: when a unit is
opened with this flag set, the printer is
not primed, and no check is made to see that
the printer is online. This can only be used
to pass ioctls. (giving us /dev/lpctl?)
- lptcontrol.c use /dev/lpctl? (LP_BYPASS)
-f flag removed, -u flag added
- lptcontrol.8 document changes in lptcontrol
rewrite using mandoc macros

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.

added new /dev/wt entries for wt.c version 1.3
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
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.
Thanks to all who helped to test it on the following hardware:

other tools really want.
Targets sio*) and com*) now create entry named ttyxx, default setup with
a sh MAKEDEV all is to use the sio major numbers, com is all but depreicated
now.
