queues for TIOCSETA[W]. Swapping an even number of times broke
the queue resource limits. This would have broken CRTSCTS flow
control if the clist slush list was used up.
Don'concatenate the queues for TIOCSETA[W] if one of the queues
has a resource limit of 0. Concatenation would cause a panic if
one of the queues is nonempty and the other is limited to length
0. This may have caused panics in PPPDISC.
Wake up readers after all transitions of ICANON. When ICANON is
turned off it is quite likely that characters will become available
to be read.
Reduce indentation near these changes.
1024 that used to remain on a line of its own after savecore completed
its job will be overwritten later in the /etc/rc process.

on output below low water) and TS_SO_OCOMPLETE (sleep on output complete).
Most of the support for this has already been committed. Drivers should
call ttwwakeup() to handle wakeups whenever output is below low water
(and some output event causes this condition to be checked) or TS_BUSY is
cleared.
tty.c:
Fix the livelock in ttywait() properly by sleeping on output complete, not
on output below low water.
Use ttwwakeup() instead of separate select and output wakeups for all
wakeups of writers.
Add wakeups of writers for output flushes and carrier/clocal transitions.
Don't go to sleep in ttycheckoutq() if ttstart() reduces the queue to below
low water.
Use the timeout built into tsleep() in ttycheckoutq().
Optimize the select wakeup in ttwwakeup(). It seems reasonable to know
too much about the internals of tp->t_wsel now that the knowledge is
localised in tty.c.
FTP_PASSIVE_MODE. It would be really nice if we could standardise on
this name so that all tools (like ncftp) that offer passive/active
ftp selection would work seamlessly with one user environment variable
setting.
Running there you got any kind of strange errors from tar caused
by treating directories as tar files!
Fix it by adding new isfile(name) (check for reg. files) to simple fexists(name) calls.
pkg_manage silently dumps core, pkg_info claims about them to
stderr, which makes very difficult to find what directory cause it via
tons of pkg_info -a output. I found solution which covers both variants,
now pkg_info claims about missing files to stdout among valid output
with ERROR: prefix. It heals pkg_manage to not dump core and makes
easy to find errors in pkg_info -a output by simple /ERROR 'more' command.
Look at error return of kread() and stop on error.
Fix warning in kread() to not output "kvm_read:" twice.
Killed PCB cache misses stat as we no longer have it.

should be closer to 2.0.5R now. I'll try to be faster for future updates...

Remove nullmodem().
It may be useful to have a null modem routine, but nullmodem()
wasn't one. nullmodem() was identical to ttymodem() except it
didn't implement MDMBUF (carrier) flow control, didn't do any
wakeups for off to on carrier transitions, and didn't flush the
i/o queues for on to off carrier transitions (flushing has the side
effect of waking up readers and writers) although it did generate
SIGHUPs. The wakeups must normally be done even if nullmodem() is
null in case something is sleeping waiting for a carrier transition.
In any case, the wakeups should be harmless. They may cause bogus
results for select(), but select() is already bogus for nonstandard
line disciplines.
Move `Individual slices' case earlier so that it can be used to handle
sliced floppies.
Remove superfluous `chmod 600's.
Fix formatting of device list.
Don't group setting of umasks with setting of units.
Remove superfluous trailing semicolons.
essential when I fix excessive wakeups for output-below-low-water.
In cy.c and sio.c, wake up via the driver start routine to also
eliminate duplicated code involving the clearing of TS_TTSTOP.
Always (except in code to be replaced soon) call driver start
routine directly instead of going through ttstart().
Amancio. There is some SoundSource support here that is primitive and
probably doesn't work, but I'll let the two submitters let me know
how my integration of that was since I don't have this card to test.
I've only tested this on my GUS MAX since it's all I have.
This all probably needs to be re-done anyway since we're widely variant
from the original VOXWARE source in the current layout.
