.Sh NAME
.Nm kbdcontrol
.Nd a utility for manipulating the syscons console driver
.Sh SYNOPSIS
.Nm
.Op Fl dFKix
.Oo
.Fl b
.Ar duration . Ns Ar pitch | Ar belltype
.Oc
.Oo
.Fl r
.Ar delay . Ns Ar repeat | Ar speed
.Oc
.Op Fl l Ar keymap_file
.Op Fl f Ar # Ar string
.Op Fl h Ar size
.Op Fl k Ar keyboard_device
.Op Fl L Ar keymap_file
.Sh DESCRIPTION
The
.Nm
command is used to set various keyboard related options for the
.Xr syscons 4
console driver and the keyboard drivers,
such as key map, keyboard repeat and delay rates, bell
characteristics etc.
.Pp
Keyboard options may be automatically configured at system boot time by
setting variables in
.Pa /etc/rc.conf .
See
.Sx Boot Time Configuration
below.
.Pp
The following command line options are supported:
.Bl -tag -width indent
.It Fl b Xo
.Ar duration . Ns Ar pitch | Ar belltype
.Xc
Set the bell duration in milliseconds and pitch in hertz.
If a
.Ar belltype
argument is specified, it may be one of
.Cm normal
which sets sound parameters back to normal values,
.Cm off
which disables the bell entirely, or
.Cm visual
which sets the bell to visual mode, i.e. flashes the screen instead.
If
.Ar belltype
is preceded by the word
.Cm quiet. ,
the bell will not be rung when the ringing process is in the background vty.
.It Fl r Xo
.Ar delay . Ns Ar repeat | Ar speed
.Xc
Set keyboard
.Ar delay
(250, 500, 750, 1000)
and
.Ar 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
.Ar speed
argument is specified, it may be one of
.Cm slow
(1000.504),
.Cm fast
(250.34)
or
.Cm normal
(500.126).
.It Fl l Ar keymap_file
Install keyboard map file from
.Ar keymap_file .
You may load the keyboard map file from a menu-driven command,
.Xr kbdmap 1 .
.It Fl 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
.Fl l
option above.
.It Fl f Ar # Ar string
Set function key number
.Ar #
to send
.Ar string .
Refer to the man page for the keyboard driver
(e.g.\&
.Xr atkbd 4 )
for available function keys and their numbers.
.It Fl F
Set function keys back to the standard definitions.
.It Fl x
Use hexadecimal numbers in keyboard map dump.
.It Fl h Ar size
Set history buffer size to
.Ar size
lines.
.It Fl i
Print brief information about the keyboard.
.It Fl K
Disconnect the keyboard from the console.
You need to use the
.Fl k
option below to associate a keyboard with the console again.
.It Fl k Ar keyboard_device
Use the specified device as the console keyboard.
When using this option, the standard input of the
.Nm
process should be redirected from
.Pa /dev/console
if you are not working on the system console
(see the
.Sx EXAMPLES
section).
.It Fl L Ar keymap_file
Load keyboard map file from
.Ar keymap_file
and write the
.Ft "struct keymap"
compiled from it to stdout.
This option is primarily intended for programmers and is probably
of little use under normal circumstances.
.El
.Sh KEYBOARD CONFIGURATION
.Ss Boot Time Configuration
You may set variables in
.Pa /etc/rc.conf
or
.Pa /etc/rc.conf.local
in order to configure the keyboard at boot time.
The following is the list of relevant variables.
.Pp
.Bl -tag -width foo_bar_var -compact
.It Ar keymap
Specifies a keyboard map file for the
.Fl l
option.
.It Ar keyrate
Sets the keyboard repeat rate for the
.Fl r
option.
.It Ar keychange
Lists function key strings for the
.Fl f
option.
.El
.Pp
See
.Xr rc.conf 5
for details.
.Ss 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.\&
.Xr atkbd 4 ,
.Xr ukbd 4 )
for details.
.Sh FILES
.Bl -tag -width /usr/share/syscons/keymaps/foo_bar -compact
.It Pa /usr/share/syscons/keymaps/*
keyboard map files
.El
.Sh EXAMPLES
The following command will load the keyboard map file
.Pa /usr/share/syscons/keymaps/ru.koi8-r.kbd .
.Pp
.Dl kbdcontrol -l /usr/share/syscons/keymaps/ru.koi8-r.kbd
.Pp
So long as the keyboard map file resides in
.Pa /usr/share/syscons/keymaps ,
you may abbreviate the file name as
.Pa ru.koi8-r .
.Pp
.Dl kbdcontrol -l ru.koi8-r
.Pp
The following command will make the function key 10 emit "telnet myhost".
.Pp
.Dl kbdcontrol -f 10 \&"telnet myhost\&"
.Pp
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 following command.
.Pp
.Dl kbdcontrol -b quiet.visual
.Pp
To change the default console keyboard to another keyboard,
for example the first USB keyboard (see
.Xr ukbd 4 ) ,
use the following commands.
.Pp
.Dl kbdcontrol -k /dev/kbd1 < /dev/console
.Pp
To switch back to the default keyboard, use this command.
.Pp
.Dl kbdcontrol -k /dev/kbd0
