39.Sh DESCRIPTION
40The
41.Nm
42command is used to set various keyboard related options for the
43.Xr syscons 4
44or
45.Xr vt 4
46console driver and the keyboard drivers,
47such as key map, keyboard repeat and delay rates, bell
48characteristics etc.
49.Pp
50Keyboard options may be automatically configured at system boot time by
51setting variables in
52.Pa /etc/rc.conf .
53See
54.Sx Boot Time Configuration
55below.
56.Pp
57The following command line options are supported:
58.Bl -tag -width indent
59.It Fl A Ar name
60Detach the keyboard, specified by the keyboard device name, from the keyboard
61multiplexer.
62When using this option, the standard input of the
63.Nm
64process should be redirected from the keyboard multiplexer keyboard device
65(if the keyboard multiplexer is not the active keyboard) or
66.Pa /dev/console
67(if the keyboard multiplexer is the active keyboard and
68you are not working on the system console).
69.It Fl a Ar name
70Attach the keyboard, specified by the keyboard device name, to the keyboard
71multiplexer.
72When using this option, the standard input of the
73.Nm
74process should be redirected from the keyboard multiplexer keyboard device
75(if the keyboard multiplexer is not the active keyboard) or
76.Pa /dev/console
77(if the keyboard multiplexer is the active keyboard and
78you are not working on the system console).
79.It Fl b Xo
80.Ar duration . Ns Ar pitch | Ar belltype
81.Xc
82Set the bell duration in milliseconds and pitch in hertz.
83If a
84.Ar belltype
85argument is specified, it may be one of
86.Cm normal
87which sets sound parameters back to normal values,
88.Cm off
89which disables the bell entirely, or
90.Cm visual
91which sets the bell to visual mode, i.e., flashes the screen instead.
92If
93.Ar belltype
94is preceded by the word
95.Cm quiet. ,
96the bell will not be rung when the ringing process is in the background vty.
97The
98.Cm visual
99bell, when chosen, applies to all vtys; other bell types
100can be set individually for each vty.
101.It Fl r Xo
102.Ar delay . Ns Ar repeat | Ar speed
103.Xc
104Set keyboard
105.Ar delay
106(250, 500, 750, 1000)
107and
108.Ar repeat
109(34, 38, 42, 46, 50, 55, 59, 63, 68, 76, 84, 92, 100, 110, 118, 126,
110136, 152, 168, 184, 200, 220, 236, 252, 272, 304, 336, 368, 400, 440,
111472, 504)
112rates, or if a
113.Ar speed
114argument is specified, it may be one of
115.Cm slow
116(1000.504),
117.Cm fast
118(250.34)
119or
120.Cm normal
121(500.126).
122.It Fl l Ar keymap_file
123Install keyboard map file from
124.Ar keymap_file .
125You may load the keyboard map file from a menu-driven command,
126.Xr kbdmap 1 .
127The format of keyboard map files is documented in the
128.Xr kbdmap 5
129manual page.
130.It Fl d
131Dump the current keyboard map onto stdout.
132The output may be redirected to a file and can be loaded
133back to the kernel later by the
134.Fl l
135option above.
136.It Fl f Ar # Ar string
137Set function key number
138.Ar #
139to send
140.Ar string .
141Refer to the man page for the keyboard driver
142(e.g.\&
143.Xr atkbd 4 )
144for available function keys and their numbers.
145.It Fl F
146Set function keys back to the standard definitions.
147.It Fl x
148Use hexadecimal numbers in keyboard map dump.
149.It Fl i
150Print brief information about the keyboard.
151.It Fl K
152Disconnect the keyboard from the console.
153You need to use the
154.Fl k
155option below to associate a keyboard with the console again.
156.It Fl k Ar keyboard_device
157Use the specified device as the console keyboard.
158When using this option, the standard input of the
159.Nm
160process should be redirected from
161.Pa /dev/console
162if you are not working on the system console
163(see the
164.Sx EXAMPLES
165section).
166.It Fl L Ar keymap_file
167Load keyboard map file from
168.Ar keymap_file
169and write the
170.Ft "struct keymap"
171compiled from it to stdout.
172This option is primarily intended for programmers and is probably
173of little use under normal circumstances.
174.It Fl P Ar path
175Search for the keymap file in
176.Ar path .
177The
178.Fl P
179option may be specified multiple times.
180.El
181.Sh ENVIRONMENT
182The environment variable
183.Ev KEYMAP_PATH
184can hold an alternative path to the keyboard map files.
185.Sh KEYBOARD CONFIGURATION
186.Ss Boot Time Configuration
187You may set variables in
188.Pa /etc/rc.conf
189or
190.Pa /etc/rc.conf.local
191in order to configure the keyboard at boot time.
192The following is the list of relevant variables.
193.Pp
194.Bl -tag -width foo_bar_var -compact
195.It Ar keymap
196Specifies a keyboard map file for the
197.Fl l
198option.
199.It Ar keyrate
200Sets the keyboard repeat rate for the
201.Fl r
202option.
203.It Ar keychange
204Lists function key strings for the
205.Fl f
206option.
207.El
208.Pp
209See
210.Xr rc.conf 5
211for details.
212.Ss Driver Configuration
213The keyboard device driver may let you change default configuration
214options, such as the default keyboard map, so that you do not need to set up
215the options at boot time.
216See keyboard driver manuals
217(e.g.\&
218.Xr atkbd 4 ,
219.Xr ukbd 4 )
220for details.
221.Sh FILES
222.Bl -tag -width /usr/share/syscons/keymaps/foo_bar -compact
223.It Pa /usr/share/syscons/keymaps/*
224keyboard map files for syscons
225.It Pa /usr/share/vt/keymaps/*
226keyboard map files for vt
227.El
228.Sh EXAMPLES
229The following command will load the keyboard map file
230.Pa /usr/share/syscons/keymaps/ru.koi8-r.kbd .
231.Pp
232.Dl kbdcontrol -l /usr/share/syscons/keymaps/ru.koi8-r.kbd
233.Pp
234So long as the keyboard map file resides in
235.Pa /usr/share/syscons/keymaps
236(if using
237.Xr syscons 4 ) or
238.Pa /usr/share/vt/keymaps
239(if using
240.Xr vt 4 ) ,
241you may abbreviate the file name as
242.Pa ru.koi8-r .
243Since
244.Xr vt 4
245uses Unicode, the corresponding keyboard file names omit the encoding
246and typically are just a country code, e.g.\&
247.Pa ru .
248.Pp
249.Dl kbdcontrol -l ru.koi8-r
250.Pp
251The following command will make the function key 10 emit "telnet myhost".
252.Pp
253.Dl kbdcontrol -f 10 \&"telnet myhost\&"
254.Pp
255In order to get the visual effect for bell, but prevent the screen
256from flashing if the bell is to ring in the background screen,
257run the following command.
258.Pp
259.Dl kbdcontrol -b quiet.visual
260.Pp
261To change the default console keyboard to another keyboard,
262for example the first USB keyboard (see
263.Xr ukbd 4 ) ,
264use the following command.
265.Pp
266.Dl kbdcontrol -k /dev/ukbd0 < /dev/console
267.Pp
268To switch back to the default keyboard, use this command.
269.Pp
270.Dl kbdcontrol -k /dev/kbd0
271.Pp
272To allow using both the second USB keyboard and the first AT keyboard
273at the same time on console via the
274.Xr kbdmux 4
275driver, use the following sequence of commands.
276.Bd -literal -offset indent
277kbdcontrol -K < /dev/console
278kbdcontrol -a atkbd0 < /dev/kbdmux0
279kbdcontrol -a ukbd1 < /dev/kbdmux0
280kbdcontrol -k /dev/kbdmux0 < /dev/console
