  --------------------------------------------------------------------------

       Notes:         This service can position the cursor on the active
                      display page or on an inactive page.

                      In graphics modes, this service sets the logical
                      position of the cursor, even though the cursor
                      itself is not displayed (there is no cursor display
                      in any graphics mode).

                      To make the cursor invisible, position it on row 25.

                      The upper left corner of the display is DH = 0h, DL
                      = 0h, while the lower right corner is DH = 18h (24),
                      DL = 27h (39) for 40-column mode or 4Fh (79) for 80-
                      column mode.

                      See Service 05h for a list of legal page numbers for
                      the different display modes. Because the service
                      does no value checking, erratic results can occur if
                      you specify an illegal page number. The page number
                      for graphics modes is 0.
