     53 /*
     54  * The kiockey structure apparently gets and/or sets keyboard mappings.
     55  * It seems to be kind of useless, but X11 uses it (according to the
     56  * comments) to figure out when a Sun 386i has a type-4 keyboard but
     57  * claims to have a type-3 keyboard.  We need just enough to cause the
     58  * appropriate ioctl to return the appropriate magic value.
     59  *
     60  * KIOCGETKEY fills in kio_entry from kio_station.  Not sure what tablemask
     61  * is for; X sets it before the call, so it is not an output, but we do not
     62  * care anyway.  KIOCSDIRECT is supposed to tell the kernel whether to send
     63  * keys to the console or to X; we just send them to X whenever the keyboard
     64  * is open at all.  (XXX may need to change this later)
     65  *
     66  * Keyboard commands and types are defined in kbd.h as they are actually
     67  * real hardware commands and type numbers.
