INT 10 - VIDEO - SET TEXT-MODE CURSOR SHAPE
AH = 01h
CH = bit 7    should be zero
bits 6,5 cursor blink
(00=normal, 01=invisible, 10=erratic, 11=slow)
(00=normal, other=invisible on EGA/VGA)
bits 4-0 top scan line containing cursor
CL = bottom scan line containing cursor (bits 0-4)
Notes:  buggy on EGA systems--BIOS remaps cursor shape in 43 line modes, but
returns unmapped cursor shape
UltraVision scales size to the current font height by assuming 14-line
monochrome and 8-line color fonts; this call is not valid if cursor
emulation has been disabled
applications which wish to change the cursor by programming the
hardware directly on EGA or above should call INT 10/AX=1130h or
read 0040h:0085h first to determine the current font height
BUG:    AMI 386 BIOS and AST Premier 386 BIOS will lock up the system if AL
is not equal to the current video mode
