kbdcontrol —
keyboard control and configuration utility
kbdcontrol |

name] [-a
name] [-b

[-k keyboard_device]
[-L keymap_file]
[-P path] |
The kbdcontrol command is used to set various keyboard
related options for the
syscons(4)
or vt(4)
console driver and the keyboard drivers, such as key map, keyboard repeat and
delay rates, bell characteristics etc.
Keyboard options may be automatically configured at system boot
time by setting variables in /etc/rc.conf. See
Boot Time Configuration
below.
The following command line options are supported:
-A
name
- Detach the keyboard, specified by the keyboard device name, from the
keyboard multiplexer. When using this option, the standard input of the
kbdcontrol process should be redirected from the
keyboard multiplexer keyboard device (if the keyboard multiplexer is not
the active keyboard) or /dev/console (if the
keyboard multiplexer is the active keyboard and you are not working on the
system console).
-a
name
- Attach the keyboard, specified by the keyboard device name, to the
keyboard multiplexer. When using this option, the standard input of the
kbdcontrol process should be redirected from the
keyboard multiplexer keyboard device (if the keyboard multiplexer is not
the active keyboard) or /dev/console (if the
keyboard multiplexer is the active keyboard and you are not working on the
system console).
-b
duration.pitch |
belltype
- Set the bell duration in milliseconds and pitch in hertz. If a
belltype argument is specified, it may be one of
normal which sets sound parameters back to normal
values, off which disables the bell entirely, or
visual which sets the bell to visual mode, i.e.,
flashes the screen instead. If belltype is preceded
by the word quiet. , the bell will not be rung when
the ringing process is in the background vty. The
visual bell, when chosen, applies to all vtys;
other bell types can be set individually for each vty.
-r
delay.repeat |
speed
- Set keyboard delay (250, 500, 750, 1000) and
repeat (34, 38, 42, 46, 50, 55, 59, 63, 68, 76, 84,
92, 100, 110, 118, 126, 136, 152, 168, 184, 200, 220, 236, 252, 272, 304,
336, 368, 400, 440, 472, 504) rates, or if a speed
argument is specified, it may be one of
slow
(1000.504), fast (250.34) or
normal (500.126).
-l
keymap_file
- Install keyboard map file from keymap_file. You may
load the keyboard map file from a menu-driven command,
kbdmap(1).
The format of keyboard map files is documented in the
kbdmap(5)
manual page.
-d
- Dump the current keyboard map onto stdout. The output may be redirected to
a file and can be loaded back to the kernel later by the
-l option above.
-f
# string
- Set function key number # to send
string. Refer to the man page for the keyboard
driver (e.g.
atkbd(4))
for available function keys and their numbers.
-F
- Set function keys back to the standard definitions.
-x
- Use hexadecimal numbers in keyboard map dump.
-i
- Print brief information about the keyboard.
-K
- Disconnect the keyboard from the console. You need to use the
-k option below to associate a keyboard with the
console again.
-k
keyboard_device
- Use the specified device as the console keyboard. When using this option,
the standard input of the
kbdcontrol process
should be redirected from /dev/console if you are
not working on the system console (see the
EXAMPLES section).
-L
keymap_file
- Load keyboard map file from keymap_file and write
the struct keymap compiled from it to stdout. This
option is primarily intended for programmers and is probably of little use
under normal circumstances.
-P
path
- Search for the keymap file in path. The
-P option may be specified multiple times.
The environment variable KEYMAP_PATH can hold an
alternative path to the keyboard map files.
You may set variables in /etc/rc.conf or
/etc/rc.conf.local in order to configure the keyboard
at boot time. The following is the list of relevant variables.
- keymap
- Specifies a keyboard map file for the
-l
option.
- keyrate
- Sets the keyboard repeat rate for the
-r
option.
- keychange
- Lists function key strings for the
-f option.
See
rc.conf(5)
for details.
The keyboard device driver may let you change default configuration options,
such as the default keyboard map, so that you do not need to set up the
options at boot time. See keyboard driver manuals (e.g.
atkbd(4),
ukbd(4))
for details.
- /usr/share/syscons/keymaps/*
- keyboard map files for syscons
- /usr/share/vt/keymaps/*
- keyboard map files for vt
The following command will load the keyboard map file
/usr/share/syscons/keymaps/ru.koi8-r.kbd.
kbdcontrol -l
/usr/share/syscons/keymaps/ru.koi8-r.kbd
So long as the keyboard map file resides in
/usr/share/syscons/keymaps (if using
syscons(4))
or /usr/share/vt/keymaps (if using
vt(4)), you
may abbreviate the file name as ru.koi8-r. Since
vt(4) uses
Unicode, the corresponding keyboard file names omit the encoding and
typically are just a country code, e.g. ru.
kbdcontrol -l ru.koi8-r
The following command will make the function key 10 emit
"telnet myhost".
kbdcontrol -f 10 "telnet
myhost"
In order to get the visual effect for bell, but prevent the screen
from flashing if the bell is to ring in the background screen, run the
following command.
kbdcontrol -b
quiet.visual
To change the default console keyboard to another keyboard, for
example the first USB keyboard (see
ukbd(4)),
use the following command.
kbdcontrol -k /dev/ukbd0 <
/dev/console
To switch back to the default keyboard, use this command.
kbdcontrol -k /dev/kbd0
To allow using both the second USB keyboard and the first AT
keyboard at the same time on console via the
kbdmux(4)
driver, use the following sequence of commands.
kbdcontrol -K < /dev/console
kbdcontrol -a atkbd0 < /dev/kbdmux0
kbdcontrol -a ukbd1 < /dev/kbdmux0
kbdcontrol -k /dev/kbdmux0 < /dev/console
