<p><b>Notes:</b>
Called by INT 09 handler to translate scan codes; the INT 09 code does
not examine the scan code it reads from the keyboard until after
this function returns. This permits software to rearrange the
keyboard; for example, swapping the CapsLock and Control keys, or
turning the right Shift key into Enter..
DOS 6 KEYB.COM will not pass through this function if Ctrl-Alt-Del is
pressed and a SmartDrive v4-compatible cache is installed which has
dirty cache buffers; some other disk caches such as HyperDisk
operate similarly in order to prevent loss of cached data which has
not yet been written to disk.
IBM classifies this function as required
