INT 10h, Function AH = 12h, FL = FBh: Return Pointer to Current Display Pa-
rameters
FONTMAP
Specific to NORAND computers, may not be PC compatible.
Returns a pointer to the 16Ćline display parameter packet and font information
for the 16Ćline display only.
On Entry:
AH = 12h
BL = 0FBh
On Return:
ES:DI = Points at the 16Ćline display parameter packet
CX = Maximum number of programmable characters
(if CX = 0, DS:SI and BH have no meaning)
DS:SI = Points at current font table
BH = Number of bytes per character in font table
INT 10h, Function AX = 12DDh, BL = FCh: Return Invert Mode
FONTMAP
Specific to NORAND computers, may not be PC compatible.
On Entry:
AH = 12h
AL = 0DDh
BL = 0FCh
On Return:
AL = Nonzero = Invert mode set
INT10h, Function AX = 12DEh, BL = FCh: Enable Invert Mode
FONTMAP
Specific to NORAND computers, may not be PC compatible.
Enables character mapping of character codes above 128 by subtracting 128
from the character code. The character is then displayed in inverse video,
mapped as character codes 0 through 127.
On Entry:
AH = 12h
AL = 0DEh
BL = 0FCh
On Return:
None
INT 10h, Function AX = 12DFh, BL = FCh: Disable Invert Mode
FONTMAP
Specific to NORAND computers, may not be PC compatible.
Disables character mapping of character codes above 128. The character is then
displayed as an extended character by use of the attribute byte.
On Entry:
AH = 12h
AL = 0DFh
BL = 0FCh
On Return:
None
