.Sh NAME
.Nm kbdmux
.Nd "keyboard multiplexer"
.Sh SYNOPSIS
.Cd "device kbdmux"
.Pp
In
.Pa /boot/device.hints :
.Cd hint.kbdmux.0.disabled="1"
.Sh DESCRIPTION
The
.Nm
keyboard driver provides support for basic keyboard multiplexing.
It is built around the idea of a
.Dq "super keyboard" .
The
.Nm
driver
acts as a master keyboard consuming input from all slave keyboards attached to
it.
.Pp
Slave keyboards can be attached to or detached from the
.Nm
keyboard driver with the
.Xr kbdcontrol 1
utility.
.Sh SEE ALSO
.Xr kbdcontrol 1 ,
.Xr atkbd 4 ,
.Xr syscons 4 ,
.Xr ukbd 4 ,
.Xr vt 4
.Sh HISTORY
The
.Nm
module was implemented in
.Fx 6.0 .
.Sh AUTHORS
.An Maksim Yevmenkin Aq m_evmenkin@yahoo.com
.Sh CAVEATS
The
.Nm
keyboard driver switches all slave keyboards into
.Dv K_RAW
mode.
Thus all slave keyboards attached to the
.Nm
keyboard share the same state.
The
.Nm
keyboard is logically equivalent to one keyboard with lots of duplicated keys.
