NAME

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

SYNOPSIS

       setkeycodes scancode keycode [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.
