     44  * The following is a minimal emulation of Sun's `kio' structures
     45  * and related operations necessary to make X11 happy (i.e., make it
     46  * compile, and make old X11 binaries run).

     49 /*
     50  * The kiockey structure apparently gets and/or sets keyboard mappings.
     51  * It seems to be kind of useless, but X11 uses it (according to the
     52  * comments) to figure out when a Sun 386i has a type-4 keyboard but
     53  * claims to have a type-3 keyboard.  We need just enough to cause the
     54  * appropriate ioctl to return the appropriate magic value.
     55  *
     56  * KIOCGETKEY fills in kio_entry from kio_station.  Not sure what tablemask
     57  * is for; X sets it before the call, so it is not an output, but we do not
     58  * care anyway.  KIOCSDIRECT is supposed to tell the kernel whether to send
     59  * keys to the console or to X; we just send them to X whenever the keyboard
     60  * is open at all.  (XXX may need to change this later)
     61  *
     62  * Keyboard commands and types are defined in kbd.h as they are actually
     63  * real hardware commands and type numbers.
