INT 10 - VIDEO - GET CURSOR POSITION AND SIZE                                   
	AH = 03h
	BH = page number
	    0-3 in modes 2&3
	    0-7 in modes 0&1
	    0 in graphics modes
Return: AX = 0000h (Phoenix BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly.)
	CH = start scan line
	CL = end scan line
	DH = row (00h is top)
	DL = column (00h is left)
Notes:	a separate cursor is maintained for each of up to 8 display pages
	many ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. BIOSes incorrectly return the default size for a color display
	  (start 06h, end 07h) when a monochrome display is attached
	With PhysTechSoft's PTS ROM-DOS the BH value is ignored on entry.
