If the software text cursor is selected (BX = 0), the masks in CX and DX are mapped as follows:Defines the shape and attributes of the mouse pointer in text modes.
Call with:
AX = 000AH
BX = pointer type
0 = software cursor
1 = hardware cursor
CX = AND mask value (if BX = 0) or
starting line for cursor (if BX = 1)
DX = XOR mask value (if BX = 0) or
ending line for cursor (if BX = 1)
Returns:
Nothing
Notes:
If the software text cursor is selected (BX = 0), the masks in CX and DX are mapped as follows:
Bit(s) Significance 0—7 character code 8—10 foreground color 11 intensity 12—14 background color 15 blink
For example, the following values would yield a software mouse cursor that inverts the foreground and background colors:
AX = 000AH
BX = 0000H
CX = 77FFH
DX = 7700H
When the hardware text cursor is selected (BX = 1), the values in CX and DX are the starting and ending scan lines for the blinking cursor generated by the video adapter. The maximum scan line which may be used depends on the type of adapter and the current display mode.
