.Sh NAME
.Nm kcon
.Nd pcvt keyboard control and remapping
.Sh SYNOPSIS
.Nm
.Op Fl d Ar delay
.Op Fl l
.Op Fl m Ar map
.Op Fl o
.Op Fl p
.Op Fl R
.Op Fl r Ar rate
.Op Fl s
.Op Fl t Ns Ar +/-
.Op Fl x
.Sh DESCRIPTION
The
.Nm
utility
is used for controlling all aspects of keyboard configuration for the 'pcvt'
video driver.
.Pp
The available options are:
.Bl -tag -width flag
.It Fl d Ar delay
Specifies the delay after which the last key entered will be repeated by the
Keyboard.
Valid values are 0..3 corresponding to delays of 250, 500, 750 and
1000 milliseconds.
.It Fl l
Displays the current keyboard map in use by the driver.
.It Fl m Ar map
Specifies the map entry to be searched in the keyboard capabilities database
.Nm keycap .
The database is searched for the entry and if found, the mapping
is loaded and is used in the driver from then on.
.It Fl o
Switches display of control codes to octal in the listing of the current map.
To be used in conjunction with the
.Fl l
option.
.It Fl p
Uses 'pure' output when listing - the Escape character is displayed in either
octal or hexadecimal and not as 'ESC'. To be used in conjunction with the
.Fl l
option.
.It Fl r Ar rate
Specifies the character repetition rate.
Valid argument values are 0...31
corresponding to rates of 30 characters/second ... 2 characters/second.
.It Fl R
Reset the Keyboard.
.It Fl s
Displays the current settings of the rate and delay values.
.It Fl t Ar +/-
Specify this option to enable
.Pq Ar +
or disable
.Pq Ar -
the repetition of keys.
.It Fl x
Switches display of control codes to hexadecimal in the listing of the current map.
To be used in conjunction with the
.Fl l
option.
This is the default behaviour.
.El
.Sh FILES
.Bl -tag -width /usr/share/misc/keycap.pcvt -compact
.It Pa /usr/share/misc/keycap.pcvt
Keyboard capabilities data base file if nothing else was chosen during installation.
.It Pa /dev/console
Keyboard raw device.
.El
.Sh SEE ALSO
.Xr keycap 3 ,
.Xr keycap 5
.Sh BUGS
The
.Nm
utility detects several inconsistencies in the keycap database.
In case of errors
.Nm
exits with an error message.
If this happens, the keyboard may remain in
an undefined state.
To recover from such situation, execute
.Dq Li kcon -m default .
.Sh EXAMPLES
The command
.Dq Li kcon -m gb
loads the entry 'gb' from the keycap file into the keyboard to switch to
a british keyboard behaviour.
.Pp
The command
.Dq Li kcon -r 0 -d 0
switches the keyboard to emit characters at a rate of 30 characters per second
after a key has been held down for 250 milliseconds.
