NAME

       setkeycodes - load kernel scancode-to-keycode mapping table entries

SYNOPSIS

       setkeycodes scancode keycode ...

DESCRIPTION

       The setkeycodes command reads its arguments two at a time, each pair of
       arguments consisting of a scancode (given in hexadecimal) and a keycode
       (given  in  decimal).  For each such pair, it tells the kernel keyboard
       driver to map the specified scancode to the specified keycode.

       This command is useful only for people with slightly unusual keyboards,
       that  have  a few keys which produce scancodes that the kernel does not
       recognize.

THEORY

       The usual PC keyboard produces a series of scancodes for each key press
       and  key  release. (Scancodes are shown by showkey -s, see showkey(1).)
       The kernel parses this stream of scancodes, and converts it to a stream
       of  keycodes  (key  press/release  events).   (Keycodes  are  shown  by
       showkey.)  Apart from a few scancodes with special meaning,  and  apart
       from  the sequence produced by the Pause key, and apart from shiftstate
       related scancodes, and apart from the key up/down bit,  the  stream  of
       scancodes  consists  of  unescaped  scancodes  xx  (7 bits) and escaped
       scancodes e0 xx (8+7 bits).  It is hardwired in the current kernel that
       in  the  range  1-88  (0x01-0x58)  keycode  equals  scancode.  For  the
       remaining scancodes (0x59-0x7f) or scancode pairs  (0xe0  0x00  -  0xe0
       0x7f)  a  corresponding  keycode  can be assigned (in the range 1-127).
       For example, if you have a Macro key that produces e0 6f  according  to
       showkey(1), the command
              setkeycodes e06f 112
       will  assign the keycode 112 to it, and then loadkeys(1) can be used to
       define the function of this key.

OPTIONS

       None.

BUGS

       The keycodes of X have nothing to do with those of Linux.  Unusual keys
       can be made visible under Linux, but not under X.
