jtc d9789d4225 Overlay our pcvt with pcvt 3.32 sources. All of our fixes have been 
incorporated into the master sources, so it is unnecessary to resolve
all the conflicts that would occur if we let CVS "merge" the versions.

================================================================================
Release 3.32 October 1995
--------------------------------------------------------------------------------
- renamed Doc/NotesAndHints to Doc/FAQ
- TS_ASLEEP not available in FreeBSD 2.1 (FreeBSD 2.1.0 SNAP 950928)
- patch from John Kohl adding missing kbd_setmode() in switch_screen()
- implemented KDGKBMODE ioctl
- removed support for KBDGLEDS and KBDSLEDS private ioctls
- changed/updated pcvt termcap entry in Doc/Termcap
- patch from Thomas Gellekum: GL and GR did not get updated after
loading a new charset into G0..G3, fixed in pcvt_vtf.c
- patch from Charles Hannum to further cleanup the saved keyboard state
per screen patch.
- patch from Frank van der Linden to support a saved keyboard state per
screen instead of one global saved flag.
- the support for NetBSD <= 0.9 and FreeBSD <= 1.1.5.1 has been dropped since
i don't run this OS versions anymore. Not all the code supporting
this versions has been removed but it will disappear without further
notice.
- removing support for the old pccons-like handling of the Xserver, the
former option PCVT_USL_VT_COMPAT has been removed since it is
now the only supported way of running X with pcvt.
- patch from Martin Husemann for 132 cols switch support for Cirrus GD6225
- patch from Martin Husemann to support Cirrus GD6225 VGA chipsets (Notebooks)
- patch from Thomas Gellekum to introduce VT220 C1 control support
- patch from Thomas Gellekum, this fixes a problem in the scrollregion code,
only reproducable under VMS: in some cases svsp->abs_write was set
to 1 when the scrollregion was set which caused check_scroll() to
fail.
- patch from Ulf Kieber (uk1@irz301.inf.tu-dresden.de) to pcvt_conf.h to
better support changing the kernel message foreground and background
color at compile time, on monochrome diplays kernel messages are
underlined by default, so one can't distinguish between 'p' and 'q'
on some displays.
- hint from Patrick Hausen to put 'pcvt' in the kcon manual page header
- patch from Joerg to loadfont to support variable scanline values
- patch from Joerg to make the mouse emulator work again (pcvt_drv.c)
Release 3.30 July 1995
--------------------------------------------------------------------------------
- new Makefile for pcvt fonteditor Util/fed
- patch from Joerg, removing all trailing whitespace chars
- added missing ECHO definition in Util/Makefile.inc.NetBSD-current
(reported by Matthieu Herrb)
- patch from John Kohl and Douglas Crosher for NetBSD-current regarding a
changed name of an include file
Changes 3.10 -> 3.20 June 1995
--------------------------------------------------------------------------------
- updating Etc/rc.local to support path variables for pcvt utilities
- fixing some code for compile with -Wall (unused variables/ add brackets)
- patch to make pcvt work on NetBSD-current and a patch to fix a FreeBSD
bug; both from John Kohl, also a minor change from him:
I changed the auto-detect code to set PCVT_NETBSD to 102 if on
-current; I figure people can use "options PCVT_NETBSD=101" in
their config file if they need to.
- keyboard code bugfix from Jukka A. Ukkonen (ukkonen@csc.fi):
I noticed that the doreset() function in pcvt was too hasty
in expecting SELFOK answers from certain keyboards. At least
Alps Membrane seems to first respond with an ACK as expected
but then it takes a short moment for itself.
During that time the only response to any attempts to fetch
the status value is -1. If one didn't allow for a few negative
replies being received before the SELFOK, one would get the
SELFOK only when expecting the answer to KBD ID query and
right after that there would be a request to re-issue the
KBD ID query.
My patch may not be the best possible solution, but it hits
the point quite nicely. With this patch attached e.g. Alps
Membrane will be correctly recognized as an MF-II keyboard.
- adding NetBSD-current patches from John Kohl
- added ${DESTDIR} to some Makefiles (patch from Joerg)
- added support for Cirrus Logic CL-GD5430 VGA chipset 132 columns mode
- new Util/Makefile.inc for FreeBSD 2.0.5-RELEASE
- merging in changes from FreeBSD 2.0.5-RELEASE
- (internal) release beta 25 ---------------------------------------------------
- added ECHO to Makefile.inc.*BSD
- added some (!) ${DESTDIR}'s to utilities Makefiles in Util
- patch from Michael Havemester for NetBSD current later than April 21 1995,
for integration into NetBSD later than this date one has to define
a version value greater than 101, i.e. "options PCVT_NETBSD=102"
- patch from joerg:
- if pcvt is acting as the systems console avoid panics going to
the debugger while we are in process mode.
- before using svsp->vs_tty and svsp->vs_tty->t_pgrp check that
vs_tty and t_pgrp are really set, other wise one can get panics
while booting with -c in FreeBSD
- added -f to all gunzip's in Util/demo
- added destination directory to ispcvt Makefile
- moved pcvt.4 and Makefile from Doc to Util/pcvtdoc
- Util Makefile cleanup
- Util Makefile patch from Bruce Evans
- Util Makefile patch from Joerg
- updated example rc.local in directory Etc to run on a serial console
- release beta 24 --------------------------------------------------------------
- bugfix from Thomas Eberhardt: the force 24 lines enable function key
label was not updated when changing force 24 lines mode with
'scon -f on|off', this is now fixed.
- bugfix from John Kohl fixing divide by zero problem in pcvt_ext.c when
ringing the bell and pitch is 0: this avoids an integer divide
trap in supervisor mode.
- changed the default behaviour of keyboard controller delay from using
delay()/DELAY() to using dummy reads to port 0x84 because i got
keyboard hangs in X.
- bugfix: in pcvt_ext.c, MDA state restore when leaving X was lost, should
function now again.
- renamed PCVT_XSERVER to XSERVER in ispcvt.c
- bugfix in pcvt_vtf.c: renamed PCVT_USL_COMPAT to PCVT_USL_VT_COMPAT
- added '-d <device>' option to ispcvt and loadfont
- removed PCVT_NEEDPG
- almost completely removed support for 386BSD 0.1 with patchkit 0.2.4
- applied a patch from Joerg providing missing FreeBSD 2.1 functionality and
a some minor bugfixes and checks.
- provide a single place PCVT_KBD_DELAY in pcvt_hdr.h. made it configurable
via PCVT_PORTIO_DELAY to use either 6 dummy reads from port 0x84
or the delay/DELAY function of the operating system. Changed ispcvt
to report status of compile time switch.
- release beta 23 --------------------------------------------------------------
- removed some files for 386BSD as there is virtually noone outside
using it anymore
- make pcvt_ioctl.h accept "KERNEL" or "_KERNEL" for NetBSD-current
- configuration fix: patch from Rafal Boni for pcvt_vtf.c, he writes:
This patch lets one compile pcvt on a system that is lacking XSERVER
and UCONSOLE [or either?] in the config file. I found this while
trying to build a minimal floppy-based test kernel. The problem is
that roll_up and roll_down assume that PCVT_USL_COMPAT is
unconditionally set, and hence muck with parts of the video structure
that are only there if PCVT_USL_COMPAT is set.
(generalized the patch a bit so that fastscroll functionality is
not lost in case of PCVT_USL_COMPAT not being defined. -hm)
- bugfix: pcvt_ext.c switch_screen() - when switching to a 25 line charset
pure VT emulation screen which has force 24 lines set, then we have
to clear the last line on screen (bugreport from Joerg).
- added define PCVT_NONRESP_KEYB_TRY for how many times to try to detect
a non-connected keyboard. This was previously set to 100 and
Joerg reports a 5+ minutes delay for a 386 booting without keyboard.
Set to 25 now in the definition. Also made shure the messages in
the corresponding loop display only once. [doreset() in pcvt_kbd.c]
- updated kbdio utility to include the 7 us delay and added a 'what' command
detect type of MCA motherboard keyboard controller according to
Frank van Gilluwe, "The Undocumented PC", Addison Wesley, pp 273
- "Gateway 2000" problem: after some discussion on the NetBSD port-i386
mailing list about hanging keyboards, Martin Husemann sent in a
patch where each inb(CONTROLLER_DATA) is now preceeded by a
delay(6). This fixed his keyboard problem, the same was reported
from Roland McGrath for his Gateway 2000 keyboard/machine.
- patch from John Kohl for usl_vt_ioctl() in file pcvt_ext.c, he writes:
This is probably a long standing bug. tsleep() returns ERESTART
if it's interrupted. ERESTART is -1, which means that the
VT_WAITACTIVE call returns from usl_vt_ioctl() with -1,
meaning "not one of my ioctl's".
- patch from Matthieu Herrb for NetBSD-current (post 1.0) support
- patch from Joerg for FreeBSD pre-2.1 support
- added file ToDo in directory Doc
- fix for Util/Makefile.inc.NetBSD-c from Onno
- removing unnecessary Trident support code from pcvt_out.c
- fix from Onno for IST_EDGE in NetBSD-current
- patch from Thomas Eberhardt to fix the bell frequency and duration setting
for NetBSD
- some fixes from Onno van der Linden for NetBSD
- added patch for NetBSD-current from Rafal Boni and Lon Willett
- added another mega patch from Lon Willett fixing several bugs:
1 -- Misc porting changes to deal with NetBSD-current, including
a new Util/Makefile.inc.NetBSD-current.
2 -- The Control_R scancodes were being mapped to the Control_L
pcvt keynum.
3 -- FASTSCROLL/graphics-mode problem: there was a problem where
switching from a graphics screen to a text screen would corrupt
the text screen's content if it had been scrolling using the
FASTSCROLL code. (The problem is the bcopy() from kernel to
video memory was using the vs[i].Memory pointer as the source,
instead of the vs[i].Crtat pointer). This is fixed in the beta
21 release by just disabling the fast scroll code for screens
which aren't active.
The patch I'm sending you re-enables the fast scroll code on
inactive (i.e. in kernel memory) screens, saving a few cpu
cycles.
4 -- This is a big one: running multiple X servers was not
really working. The USL handshaking code was a mess (not very
well designed to begin with, but there's not much that can be
done about that). I did manage to get it fairly functional, but
there's a lot of changes.
- changing example rc.local to take care of good old EGA's
- fixing support for EGA boards in vt_coldinit()
- removing vt100 font files from Util/fonts, updated Manifest
- fixing an obviously longstanding bug in roll_up() / roll_down() which was
triggered by Joergs "Crtat" cleanup mega patch.
- removing PCVT_FAKE_SYSCONS10
- removing duplicate names in termcap entries
- fixing vt_coldinit: setting variable "color" for mda/hercules and cga
initializing cursor position
- fixing roll_up() and roll_down() for mda/hercules: mda's have ALWAYS
just one page of memory, original hercules boards too so they
can NEVER use the fastscroll option. SOME hercules are somehow
enhanced in that they support 2 pages. pcvt now just supports
one page hercules/mda!
- made cleanups to 8x14 high and 8x8 high fonts: adjust the 5 scanline
characters to adjust with the corner characters from the low fonts
- applying patch from Joerg which fixes some bugs:
writing to a tty containing an X server resulted in some stange
behaviour depending on the opsys and opsys version used
the init code preserving the screen contents and cursor shape
can only be done on boards allowing the reading of
several crtc registers
- removed bcopyb declaration from pcvt_hdr.h for FreeBSD 2.1
- another patch from Lon Willett (willett@math.utah.edu), he writes:
1 -- Very minor: One of my previous changes didn't get merged
into "pcvt_out.c"; the caclulation of ws_row doesn't account for
"force24" at one spot. It's easier to just set it from
screen_rows anyway, unless there's something that I didn't
understand happening here.
2 -- Debugging stuff: I don't know if you care to add it, but I
found it useful, so I left it in. I rearranged the
PCVT_SHOWKEYS code a little, and added a few lines to show
keyboard commands and responses, with special delimiters.
[file: pcvt_kbd.c]
3 -- "kcon" utility enhancement: I added a "-R" switch to kcon
to do a KBDRESET ioctl. [file: Util/kcon/kcon.c]
4 -- KBDRESET-ioctl bug: the code was trying to read kbd
responses without an spltty(), so naturally it would fail, since
pcrint() was grabbing the ACKs. [file: pcvt_kbd.c]
5 -- update_led() makes kbd hang: the problem here is that
update_led() makes the keyboard generate two KEYB_R_ACK
responses, and one of the interrupts sometimes gets lost when
there is a lot of other I/O happening. See the comment in the
code. My fix seems to work for me, but you may want to handle
it some other way. It would probably be quite reasonable to
check for lost interrupts periodically anyway, whether
update_led() has been called or not. [file: pcvt_kbd.c]
(NOTE: item 5 has been disabled because it causes older
FreeBSD's to panic because of the timer queue not being
initialized at the time called. -hm)
- partly rewrote doreset() in pcvt_kbd.c to enable boot procedure to proceed
if no (PC) keyboard is found. The current behaviour and implementation
is subject to change.
- patch from Thomas Gellekum to Util/keycap/keycap.src
- minor modification to main.c in Util/set2061
- patch from Onno and John Kohl to make pcvt beta 16 work on NetBSD current:
1. pcvt_conf.h
_real_ 1.0 ===> NetBSD1_0 == 1
current 1.0 (1.0A) ===> NetBSD1_0 == 2
2. pcvt_hdr.h
Put pcvt_conf.h before _all_ the #ifdef PCVT_*. This way
the #ifdef NetBSDx_y stuff can do its work.
- size of PCVT_BURST was still reported as 1 for FreeBSD 2.0, fixed
- made some adjustments for FreeBSD 2.0 in Util/vgaio
- Another patch from Joerg for FreeBSD 2.0
- included vgaio, kbdio and set2061 into the outer Makefile, this programs
are build and cleaned but don't install anything.
All program's in the Util dir should now cleanly make <anything> ...
- enable 132 column support for Trident TVGA8900CL, some NetBSDisms
- addend patch from Joerg for pcvt-320b7 to fix FreeBSD 2.0's ttymalloc's
encapsulation into #if's. Also new keycap.src entry.
- fixed keyboard status/LED not updated on soft reset emulator
- on 23rd of December i had some spare time, so i added some demos to the
Util/demo directory as well a a time-killer program (playvt) to view
some of the VT animations and a christmas animation i got from Joerg.
- added a new utility set2061 to program the clock generator on my S3 based
ELSA Winner VGA board. This eventually lets me use 132 columns on this
board, because i'm now able to program the clock to generate 40MHz
on clock output #2.
- debugged winsize patch on FreeBSD 1.1, line discipline open init's the
queues, winsize initialization must happen after line disc. open!
- got a bunch of NetBSD PR's from J.T. Conklin:
PR #214: PCVT treats ctrl-shift exactly like shift for most characters.
(fixed by Lon Willet's Mega Patch described below -hm)
PR #399: If you define PCVT_META_ESC when builting PCVT, Meta-Return
sends 0x8d instead of ESC RET.
(fixed by applying the patch from Bill Sommerfeld. -hm)
PR #400: pcvt sometimes gets confused about window size
(fixed by applying the patch from Bill Sommerfeld. -hm)
PR #404: Meta-Control-Space broken with PCVT_META_ESC and PCVT_NULLCHARS
(put into "BugList" file, no solution yet .. -hm)
PR #488: pcvt can loose keyboard control if you start an xserver from
an xterm
(already fixed by a patch from John Kohl, see below -hm)
PR #580: NetBSD i386/pcvt bugs/enhancements; fixes included
(already integrated the patch from Lon Willet, see below -hm)
- on coldinit, if FAT_CURSOR is defined, the old large blockcursor is used
- enhanced the vgaio output in an attempt to make 132 column mode work
for my S3 board ....
- applied patch from Thomas Gellekum: install instructions for FreeBSD 2.0,
patch to fontedit to compile under FreeBSD 2.0, an addition to
keycap.src and a fix for kbdio
- changed installation instructions to reflect recent changes, removed
instructions for FreeBSD 1.0 and added instructions for FreeBSD 2.0
- upgraded all utilities version strings to 3.20
- new example of rc.local
- changing timeout()/untimeout() function parameter type to TIMEOUT_FUNC_T
definition in pcvt_hdr.h
- changed install instructions to reference Etc dir instead of Doc dir for
several files which were moved from Doc to Etc.
- new parameter -d for the cursor utility, updated cursor manpage
- applying a patch from Lon Willett, willett@math.utah.edu which fixes
several bugs and provides some enhancements. Lon writes:
1 -- The displayed cursor is not updated during kernel I/O,
because async_update() doesn't get called. This is merely ugly
while the system startup messages are being displayed, but it is
positively annoying when using the kernel debugger.
2 -- CONTROL-SHIFT-<KEY> is taken to be the same as SHIFT-<KEY>.
It should be interpretted as CONTROL-<KEY>, or even have its own
binding. One of the lines below fixes it in the former way.
This is especially bad (i.e. clearly buggy) when I type
CONTROL-SHIFT-<6/^> to get a "Control-^", and instead get a "^".
3 -- The "special" region at the bottom of the screen, i.e. the
function-key-labels/status-line in HPVT mode, and the blank line
in FORCE24LINES mode, do not get properly cleared/updated.
4 -- When switching screen sizes/modes, the FORCE24LINES setting
is not always handled.
5 -- The PCVT_VT220KEYB functions are missing some features.
The control key settings are bug fixes; they apply only if
system function key labels are on, and match the labels. The
shift key definitions are enhancements.
The new keys (previously undefined) are:
Control-F1 -- toggle 80/132 columns
Control-F2 -- soft reset emulator
Control-F3 -- toggle force 24 lines mode
Control-F4 -- toggle keyboard debugging
Shift-F1 -- select screen 4
Shift-F2 -- select screen 5
Shift-F3 -- select screen 6
Shift-F4 -- select screen 7
Shift-F5 -- select (current screen - 1)
6 -- [Enhancement] The initial startup screen is cleared, and
the screen gets cleared when changing modes/sizes. I don't like
this. I want a chance to see bootstrap loader messages, and I
also want the command "scon -d/dev/ttyv0 -H -s28" in my
rc.local, but then I lose various messages from daemons, etc
(which aren't always logged to syslog). So I have fixed the
code so that it tries to preserve the contents of the screen
when starting up, and when changing modes/sizes.
7 -- [Enhancement?] I added code to preserve the initial cursor
shape at startup. This isn't really necessary, since the
"cursor" command can be used to set it to your preference; but
it seems like this is the preferable policy to use for the
default.

(new) cursor (row) position from sputc(). (Otherwise a cursor
would appear temporarily in the first position of the first
function key label in the HP mode)
- updated screeninfo ioctl and scon to report the monitor type
- added file Doc/Notes for random notes and hints for pcvt-users.
- enhanced the pcvtid-ioctl and the ispcvt(8) utility to print out the
values of all "PCVT_XXXXXX" compile time options.
- included work from Joerg to convert all ifdef's to if's, to be able
to compile various configurations of pcvt without changing
options in the header file.
- included (currently untested !) patch for a keyboard mouse emulator
from Joerg. (he got problems after he bought a notebook with
just one serial port, which he wanted to use for slip ...)
- screensaver reset is now also done asynchronously to get more speed. the
function average() was renamed to async_update().
- cursor position update and cursor position display in HP mode is now done
asynchronously in function average() in pcvt_sup.c. the function
update_cursor does no longer exist. this gave about 10..30% increase
in speed depending on the data cat'ed (termcap, kernel, 1Mb nulls)
- HP function key emulation processing debugged, this has to be rewritten
to use a stack and a new parser. elm -K now works a bit more, the
display is not garbled anymore, but fkey strings do not work.
- pcvt_vtf.c split off from pcvt_out.c, file got > 100k. Checked all
forward declarations in header and source files
- 132 column support for Cirrus Logic CL-GD542X chipsets written by
Onno van der Linden, c/o vdlinden@fwi.uva.nl
- keyboard scancode display (#define PCVT_SHOWKEYS)
- printscreen keycode fix form Onno van der Linden
- Util/Makefile.inc added .depend dependency for make depend
- pcvt_ioctl.h is now installed into /usr/include/machine.
- keyboard scancode 1 is now used by default, perhaps it cures some problems
- support for keyboard scancodes sets 1 and 2 (compile time selectable via
PCVT_SCANSET), patch from Onno van der Linden, c/o vdlinden@fwi.uva.nl
- Util/fontedit.c updated to "#if defined (__386BSD__) || defined (__NetBSD__)"
(suggested by Mark Weaver, Mark_Weaver@brown.edu)
- 132 column support for S3 86c928 chipsets
- split off pcvt_ext.c from pcvt_sup.c, it was more than 100k ....
- intro of Doc/Manifest and Doc/TestedHardware, removed README.X-PATCH because
it was now really outdated
- superprobe compatibility patches from Joerg
- intro of file Doc/BugList
- another powerpatch from Joerg:
- some vgaioctl's are now available if in X mode (i.e. to scon to
another screen from within an xterm)
- removed bug in keyboardhandling, numlock'ed numkeys did send an
additional null (0x00) char, this has been fixed now.
- SysRq key made functional
- made force 24 lines (see below) the default configuration to have a well
behaving vt220 emulator at startup.
- every vt now has a separate caps-lock, num-lock and scroll-lock flag and
a separate handling of these lock-keys.
- made sleeping in case of scroll lock working from an earlier patch from Joerg.
- large patch from Joerg:
- Doc/pcvt.4 updated to reflect recent changes
- struct winsize set ok when switching between HP/VT
- struct winsize pixels reflect real values now
- ioctl for switching between 80 and 132 cols
- 132 columns for generic VGA's
- updated scon to provide access to ioctl 80/132 col switching
- removed pcconcoftc and kbdsoftc structures from header files, removed
pcconsintr variable and introduced kbd polling synchronization
variable kbd_polling.
- merging Joerg's patch to support 132 columns on Tseng Labs ET3000
- moved Util/uemacs/* --> Etc/uemacs.tar.Z.uu
- added patches from Joerg for new Makefiles in Util
- added keyboard security define's to the new X server code
- adding bugfixes from Joerg Wunsch for "old" (= non vt switching) X server
- Control-Alt-Functionkey(1...12) switches now virtual screens/terminals to
behave consistently with xfree 2.0, also the pages are now checked
against the real no. of terminals available ALL the time ...
- pcvt_hdr.h: changed "int pcstart();" to "void pcstart();" to avoid warning
message when compiling under NetBSD-current
- Doc dir split into Doc and Etc, Support renamed to Util
- adding NetBSD-current support for new X server support (syscframe changed
to trapframe in NetBSD-current as of 11/11/93)
- adding Joergs changes for XFree86 2.0 multiple X server and/or terminal
session support
- adding entries from patchkit 0.2.4 codrv keymap to Support/keycap/keycap.src
- Keyboard security introduced into the XSERVER dependent part in pcvt_drv.c
- renamed device files from /dev/ttycXX to /dev/ttyvXX
- added file Doc/pcvt.el from Joerg Wunsch to distribution
- added HP-mode function key map from Gordon L. Burditt to description
in Doc/Keyboard.HP
- fixed bug in scon which prevents it from showing the correct status of
132 column support of chipset
- 132 column mode for Trident TVGA9000 works now, after 2 1/5 months of
calling everybody i eventually got a tech ref manual from Trident ....
- it is now possible to "force" pcvt into a 24 line mode when operating
in pure VT mode with 25 lines or in HP mode with 28 lines. This
is sometimes necessary when running software which assumes it runs
on a "real" VT220 which has just 24 lines.
- updated scon to support the 24 lines force mode (scon -f [ on | off ])
- soft reset fkey now positions cursor into left upper corner, update_cursor()
made global function
- updated scon (-l) to print out additional info about the vga chipset,
family and 132 column support if VGA detected.
- added additional fields to screeninfo structure in pcvt_ioctl.h to be
able to return information about current vga chipset.
- moved VGA type/family definitions from pcvt_hdr.h to pcvt_ioctl.h
- Terminfo and Termcap updated to support 132 columns
- fixed bug in kcon which outputs garbage for remapped keys in kcon -l.
(reported by Gordon L. Burditt, gordon@sneaky.lonestar.org)
- modified Makefile for Support/ispcvt to copy it for installation instead
of moving it ..
- renamed /usr/share/misc/keycap -> /usr/share/misc/keycap.pcvt to
avoid nameclash with same file for codrv (Gordon Burditt)
- security bit no longer ignored when initializing keyboard (see #define
PCVT_USEKBDSEC in pcvt_hdr.h, suggested by Terry Lambert)

"PCVT_" for easy identification and installation into the kernel config file
- applied another pcvt_kbd.c patchkit from Bruce Evans, bde@runx.oz.au. he
writes:
These fixes are mainly related to ddb. sgetc has a weird interface that
has caused some bugs, and it was too easy for ddb to reenter itself.
1. Don't use char for keypad2num, char might be unsigned. Space is not
important since the array is small.
2. Don't use u_short for n.
3. Change some 0's to NULLs.
4. sgetc must not return NULL for the !noblock case. Only callers with
noblock set check for the null pointer. When the kernel follows a
null pointer, I think page 0 is sometimes mapped in so nothing bad
happens. The kernel panics if the page is not mapped in.
5. Reentrancy fix. The debugger really ought to check for reentrancy
itself, but the driver still needs to return early after the
debugger returns, so that it doesn't return a junk ESC from
ctrl-alt-ESC.
6. xlatkey2ascii may return NULL too.
