.Sh DESCRIPTION
The
.Nm
utility manipulates the state of the keyboard, or displays the
keyboard type, or allows the default keyboard abort sequence effect to be
changed.
The abort sequence also applies to serial console devices.
The
.Nm
utility sets the
.Pa /dev/kbd
default keyboard device.
.Sh EXTENDED DESCRIPTION
The
.Fl i
option reads and processes default values for the keyclick and
keyboard abort settings from the keyboard configuration service,
.Sy svc:/system/keymap:default .
Only keyboards that support a clicker respond to the
.Fl c
option.
.Pp
The keyboard abort sequence effect can only be changed by a super-user using
the
.Fl a
option.
This sequence is typically Stop-A or L1-A and Shift-Pause on the keyboard on
.Sy SPARC
systems, F1-A and Shift-Pause on x86 systems,
and BREAK on the serial console input device on most systems.
.Pp
A
.Sy BREAK
condition that originates from an erroneous electrical signal
cannot be distinguished from one deliberately sent by remote
.Sy DCE .
As a remedy, use the
.Fl a
option with Alternate Break to switch break interpretation.
Due to the risk of incorrect sequence interpretation, binary
protocols such as
.Sy SLIP
and others should not be run over the serial console port when Alternate Break
sequence is in effect.
.Pp
Although PPP is a binary protocol, it has the ability to avoid using characters
that interfere with serial operation.
The default alternate break sequence is
CTRL-m
.Sy ~
CTRL-b, or
.Sy 0D 7E 02
in hexadecimal.
In PPP, this can be avoided by setting either
.Sy 0x00000004
or
.Sy 0x00002000
in the ACCM.
This forces an escape for the CTRL-b or CTRL-m characters, respectively.
.Pp
To do this in Solaris PPP 4.0, add:
.Pp
.Dl asyncmap 0x00002000
.Pp
to the
.Pa /etc/ppp/options
file or any of the other configuration files used for the connection.
See
.Xr pppd 1M .
.Pp
SLIP has no comparable capability, and must not be used if the Alternate Break
sequence is in use.
.Pp
The Alternate Break sequence has no effect on the keyboard abort.
For more information on the Alternate Break sequence, see
.Xr zs 7D ,
.Xr se 7D ,
and
.Xr asy 7D .
.Pp
On many systems, the default effect of the keyboard abort sequence is to
suspend the operating system and enter the debugger or the monitor.
Some systems feature key switches with a
.Sy secure
position.
On these systems, setting the key switch to the
.Sy secure
position overrides any software default set with this command.
.Sh OPTIONS
The following options are suported:
.Bl -hang
.It Fl a Ar enable | Ar disable | Ar alternate
.Pp
Enables, disables, or alternates the keyboard abort sequence effect.
By default, a keyboard abort sequence suspends the operating system on most
systems.
This sequence is typically
.Sy Stop-A
or
.Sy L1-A
and
.Sy Shift-Pause
on the keyboard on
.Sy SPARC
systems,
.Sy F1-A
and
.Sy Shift-Pause
on x86 systems, and
.Sy BREAK
on the serial console device.
.Pp
The default keyboard behavior can be changed using this option.
The
.Fl a
option can only be used by a super-user.
.Bl -hang
.It Ar enable
Enables the default effect of the keyboard abort sequence (suspend the
operating system and enter the debugger or the monitor).
.It Ar disable
Disables the default/alternate effect and ignores keyboard abort sequences.
.It Ar alternate
Enables the alternate effect of the keyboard abort sequences (suspend the
operating system and enter the debugger or the monitor) upon receiving the
Alternate Break character sequence on the console.
The Alternate Break sequence is defined by the drivers
.Xr asy 7D ,
.Xr se 7D ,
.Xr zs 7D .
Due to a risk of incorrect sequence interpretation, binary protocols cannot be
run over the serial console port when this value is used.
.El
.It Fl A Ar count
.Pp
Sets autorepeat count.
Value
.Sy -1
denotes unlimited autorepeat (default).
.It Fl b Ar keyboard | Ar console
.Pp
Sets the beeper frequency for keyboard or console.
.Bl -hang
.It Ar keyboard
Set the keyboard beeper frequency to the operand in HZ.
See
.Sx OPERANDS .
.It Ar console
Sets the console beeper frequency to the operand in HZ.
See
.Sx OPERANDS .
.El
.It Fl c Ar on | Ar off
.Pp
Turns the clicking of the keyboard on or off.
.Bl -hang
.It Ar on
Enables clicking
.It Ar off
Disables clicking
.El
.It Fl d Ar keyboard device
.Pp
Specifies the keyboard device being set.
The default setting is
.Pa /dev/kbd .
.It Fl D Ar autorepeat delay
.Pp
Sets the autorepeat delay in milliseconds.
.It Fl i
.Pp
Sets keyboard properties from the keyboard default file.
With the exception of
.Fl d Ar keyboard device ,
this option cannot be used with any other option.
The
.Fl i
option instructs the keyboard command to read and process
keyclick and keyboard abort default values from the keyboard configuration
service,
.Sy svc:/system/keymap:default .
The
.Fl i
option can only be used by a user or role with the
.Sy Device Security Rights Profile .
.It Fl l
.Pp
Returns the layout code of the keyboard being used, and the autorepeat delay
and autorepeat rate being used.
.Pp
If used with
.Fl R
or
.Fl D
option, this option returns the value before the changes.
.It Fl r
Resets the keyboard as if power-up.
.It Fl R Ar autorepeat rate
.Pp
Sets the autorepeat rate in milliseconds.
.It Fl s Op Ar language
.Pp
Sets the keyboard layout into the kernel.
.Pp
If
.Ar language
is specified, the layout is set to
.Ar language ,
and
.Xr loadkeys 1
runs implicitly.
If
.Ar language
is not specified, a list of available layouts are presented, prompting for the
user to specify the
.Ar language .
See
.Sx OPERANDS .
.It Fl t
.Pp
Returns the type of the keyboard being used.
.El
.Sh OPERANDS
The following operands are supported:
.Bl -hang
.It Ar frequency
The frequency value specified to be set in kernel.
The receiver of this value is specified by the
.Fl b
option.
This value should be between 0 and 32767 otherwise will be ejected with
.Sy EINVAL .
.It Ar language
The language specified to be set in kernel.
If the language is not found, the languages supported are listed for selection.
It only applies to
.Fl s
option.

.Sh NOTES
Some server systems have key switches with a
.Sy secure
key position that can be read by system software.
This key position overrides the normal default of the keyboard abort sequence
effect and changes the default so the effect is disabled.
When the key switch is in the
.Sy secure
position on these systems, the keyboard abort sequence effect cannot be
overridden by the software default, which is settable with the
.Nm
utility.
.Pp
Currently, there is no way to determine the state of the keyboard click
setting.
.Pp
The
.Nm
service is managed by the service management facility,
.Xr smf 5 ,
under the service identifier:
.Pp
.Dl svc:/system/keymap:default

Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using
.Xr svcadm 1M .
Use

to make configuration changes and to view configuration information for this
service.
The service's status can be queried using the
.Xr svcs 1
