KBDCONTROL(1)		  BSD General Commands Manual		 KBDCONTROL(1)

NAME
     kbdcontrol — keyboard control and configuration utility

SYNOPSIS
     kbdcontrol [-dFKix] [-A name] [-a name] [-b duration.pitch | belltype]
		[-r delay.repeat | speed] [-l keymap_file] [-f # string]
		[-k keyboard_device] [-L keymap_file]

DESCRIPTION
     The kbdcontrol command is used to set various keyboard related options
     for the syscons(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 mul‐
	     tiplexer 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 mul‐
	     tiplexer 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) man‐
	     ual 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 nor‐
	     mal circumstances.

ENVIRONMENT
     The environment variable KEYMAP_PATH can hold an alternative path to the
     keyboard map files.

KEYBOARD CONFIGURATION
   Boot Time Configuration
     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 rele‐
     vant 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.

   Driver Configuration
     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.

FILES
     /usr/share/syscons/keymaps/*	 keyboard map files

EXAMPLES
     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,
     you may abbreviate the file name as ru.koi8-r.

	   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
     flushing if the bell is to ring in the background screen, run the follow‐
     ing command.

	   kbdcontrol -b quiet.visual

     To change the default console keyboard to the another keyboard, for exam‐
     ple the first USB keyboard (see ukbd(4)), use the following commands.

	   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
