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
