     * The following is a minimal emulation of Sun's `kio' structures

     * compile, and make old X11 binaries run).

    /*
     * The kiockey structure apparently gets and/or sets keyboard mappings.
     * It seems to be kind of useless, but X11 uses it (according to the
     * comments) to figure out when a Sun 386i has a type-4 keyboard but
     * claims to have a type-3 keyboard.  We need just enough to cause the
     * appropriate ioctl to return the appropriate magic value.
     *
     * KIOCGETKEY fills in kio_entry from kio_station.  Not sure what tablemask
     * is for; X sets it before the call, so it is not an output, but we do not
     * care anyway.  KIOCSDIRECT is supposed to tell the kernel whether to send
     * keys to the console or to X; we just send them to X whenever the keyboard
     * is open at all.  (XXX may need to change this later)
     *
     * Keyboard commands and types are defined in kbd.h as they are actually
     * real hardware commands and type numbers.
