AH = 4Fh AL = hardware scan code (see #00006) CF set
Return:
CF set to continue processing scan code AL = possibly-altered hardware scan code (see #00006) CF clear scan code should be ignored
Notes: 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
