                   INT 10,3 - Read Cursor Position and Size

       AH = 03
       BH = video page

       on return:
       CH = cursor starting scan line (low order 5 bits)
       CL = cursor ending scan line (low order 5 bits)
       DH = row
       DL = column

       - returns data from BIOS DATA AREA locations 40:50, 40:60 and 40:61
       - the 6845 can also be used to read the cursor position
       - the return data can be circumvented by direct port I/O to the 6845
         CRT Controller since this function returns the data found in the
         BIOS Data Area without actually checking the controller
