NAME

SYNOPSIS

DESCRIPTION

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.

ENVIRONMENT

KEYBOARD CONFIGURATION

FILES

/usr/share/syscons/keymaps/*

keyboard map files for syscons

/usr/share/vt/keymaps/*

keyboard map files for vt

EXAMPLES

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
