          BX    file handle  (device or disk file; 0001H=std output)
          CL    5fH

    Info: Sets the console screen display mode (including selecting the
          width in columns and height in lines)

          Before calling, you must preset the IoctlDisplayModeRec
          bInfoLevel field to 00H and the wDataLen field to 0eH (14).

          This fn works only if the ANSI.SYS (or equivalent) device driver
          is loaded.

          When an unsupported mode is requested, AX returns with 0005H
          (access denied).
