    Command:

    setkeycodes

    
    
    

    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 scan-
           codes 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  cor-
           responding  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.
    
           USB keyboards have standardized keycodes and setkeycodes doesn't affect
           them at all.
    
    
    

    2.6 KERNELS

           In 2.6 kernels key codes lie in the range 1-255, instead of 1-127.  (It
           might be best to confine oneself to the range 1-239.)
    
           In 2.6 kernels raw mode, or scancode mode, is not very raw at all.  The
           code  returned  by  showkey -s will change after use of setkeycodes.  A
           kernel bug. See also showkey(1).
    
    
    

    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.
