VIDEO - UltraVision v1.2+ - SET UNDERLINE STATUS (EGA,VGA)

AX = CD07h
CL = hardware underline status (see #00221)
BL = foreground color for normal text (FFh = current)
BH = foreground color for bright text (FFh = current)

Return:
CL = hardware underline status BL = current foreground color for normal text BH = current foreground color for bright text

Notes: When underline or strikeout is enabled in color text modes, the specified colors will be assigned temporarily to colors 01h and 09h, allowing affected text to match non-underlined text. The color remapping uses values from the current onscreen palette regardless of the palette locking status (see AX=CD01h). Specify the standard colors (BL=01h,BH=09h) to enable underline or strikeout without color remapping

See Also: AX=CD08h

(Table 00221) Values for hardware underline status: 00h off (color systems only) 01h underline below characters 02h strike through characters
