implemented using a new VT_LOCKSWITCH ioctl. Although it is possible
to implement something like this by VT_SETMODEing to VT_PROCESS and
never releasing the vty, that method has a number of downsides, the
biggest of which is that some program has to stay resident for the
lock to be in effect.

case use size of the currently displaying font as a suffix. For example,
when the when the size of the currently displayed font is 8x8 the
following command will load koi8-r-8x8.fnt.
# vidcontrol -f koi8-r
MFC after: 2 weeks
the following fixes had been made:
- check the size of the font being loaded and compare it with possible sizes
to minimise possibility of loading something that is not a fontfile at all
and turning console screen into garbage;
- prevent buffer overflow (and coredump as a result ) when loading valid
uuencoded file with size that exceeds allocated buffer;
- correct and improve several error messages.
Approved by: -audit, -hackers (silently)
Replace all in-tree uses with necessary subset of <sys/{fb,kb,cons}io.h>.
This is also the appropriate fix for exo-tree sources.
Put warnings in <machine/console.h> to discourage use.
November 15th 2000 the warnings will be converted to errors.
January 15th 2001 the <machine/console.h> files will be removed.
- Accept generic video mode names: 80x25, 80x30, etc. Specific video
mode names, VGA_80x25, VESA_132x25, are still accpeted too.
- Update the man page accordingly.

The VESA support code requires vm86 support. Make sure your kernel
configuration file has the following line.
options "VM86"
If you want to statically link the VESA support code to the kernel,
add the following option to the kernel configuration file.
options "VESA"
The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600
The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.
vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'. When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

them as ints. Among other bugs, doing so at best caused benign
overflow followed by fatal sign extension on machines with 32-bit
ints and 64-bit longs.
life easier if a PS/2 mouse locks up the keyboard (frequent-ish,
but not repeatable).
Tidy up code (a bit) and make it -Wall
Is this a 2.2 candidate ? (although it doesn't -Wall in 2.2 because
of the lack of sys/sysproto.h
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Removed screensavers from syscons, they are now LKM's. This makes it
possible to do some really "interesting" screensavers...
Fixed bug that sometimes caused garbage to appear when leaving
"scroll-lock" history.
Reformattet indentation, it got too deep for a normal 80 pos screen.
Split up in syscons.c & syscons.h for use with the saver-lkm's.
Temporarily removed -s option from vidcontrol, savers should now
be loaded with modload.
Display update method changed, now allways write in memory buffer,
then periodically update physical display.
Speed improvements (now > 5 times faster than the old syscons).
History now circular buffer, with changeable size.
History scroll by up/down line, up/down page, home and end.
Backtab proberly implemented.
Now space for 96 function keys, 63 allocated standard, default now
SCO/SYSV compat again as in the old days.
New keyboard definition files ~share/syscons/keymaps/*
Misc fixes for old "hacks" that broke SCO/SYSV compat.
More that I forgot before writing this...
No kernel config options anymore besides keyboard language layout.
Virtual consoles are now dynamically allocated, no NCONS anymore.
Software cursor blinking/nonblinking.
Visual bell for laptops (don't beep at meetings :-).
Cursor/bell default type setable via config "flags" instead of as defines.
Cursor/bell type setable via ioctl's.
New video modes 80x30 80x60 for some laptops, and those with multisync monitors.
Scroll-lock history (length currently fixed at 100 lines).
Lots of cleanups, some only commented out for now (will goaway soon).
Support for new features in vidcontrol/kbdcontrol.
Updated manpages.
