The kbdmux keyboard driver provides
support for basic keyboard multiplexing. It is built around the idea of a
“super keyboard”. The kbdmux driver
acts as a master keyboard consuming input from all slave keyboards attached
to it.
Slave keyboards can be attached to or detached from the
kbdmux keyboard driver with the
kbdcontrol(1)
utility.
The kbdmux module was implemented in
FreeBSD 6.0.
The kbdmux keyboard driver switches all
slave keyboards into K_RAW mode. Thus all slave
keyboards attached to the kbdmux keyboard share the
same state. The kbdmux keyboard is logically
equivalent to one keyboard with lots of duplicated keys.
