.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 A Ar name
|
|
Detach the keyboard, specified by the keyboard device name, from the keyboard
|
|
multiplexer.
|
|
When using this option, the standard input of the
|
|
.Nm
|
|
process should be redirected from the keyboard multiplexer keyboard device
|
|
(if the keyboard multiplexer is not the active keyboard) or
|
|
.Pa /dev/console
|
|
(if the keyboard multiplexer is the active keyboard and
|
|
you are not working on the system console).
|
|
.It Fl a Ar name
|
|
Attach the keyboard, specified by the keyboard device name, to the keyboard
|
|
multiplexer.
|
|
When using this option, the standard input of the
|
|
.Nm
|
|
process should be redirected from the keyboard multiplexer keyboard device
|
|
(if the keyboard multiplexer is not the active keyboard) or
|
|
.Pa /dev/console
|
|
(if the keyboard multiplexer is the active keyboard and
|
|
you are not working on the system console).
|
|
.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.
|
|
The
|
|
.Cm visual
|
|
bell, when chosen, applies to all vtys; other bell types
|
|
can be set individually for each 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 .
|
|
The format of keyboard map files is documented in the
|
|
.Xr kbdmap 5
|
|
manual page.
|
|
.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 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"
|
|

|
|
This option is primarily intended for programmers and is probably
|
|
of little use under normal circumstances.
|
|
.El
|
|
.Sh ENVIRONMENT
|
|
The environment variable
|
|
.Ev KEYMAP_PATH
|
|
can hold an alternative path to the keyboard map files.
|
|
.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 flashing 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 command.
|
|
.Pp
|
|
.Dl kbdcontrol -k /dev/ukbd0 < /dev/console
|
|
.Pp
|
|
To switch back to the default keyboard, use this command.
|
|
.Pp
|
|
.Dl kbdcontrol -k /dev/kbd0
|
|
.Pp
|
|
To allow using both the second USB keyboard and the first AT keyboard
|
|
at the same time on console via the
|
|
.Xr kbdmux 4
|
|
driver, use the following sequence of commands.
|
|
.Bd -literal -offset indent
|
|
kbdcontrol -K < /dev/console
|
|
kbdcontrol -a atkbd0 < /dev/kbdmux0
|
|
kbdcontrol -a ukbd1 < /dev/kbdmux0
|
|
kbdcontrol -k /dev/kbdmux0 < /dev/console
