If you use the mouse driver from freedos, the api allows you to check for it, (read wheelapi.txt for full info) --------------------------------------------------- INT 33/0000 - Reset driver and read status Note: this call clears the wheel movement counter INT 33/0003 - Get cursor position, buttons status and wheel counter AX = 0003h Return: BL = buttons status BH = 8-bit signed counter of wheel movement since last call CX = column DX = row Notes: returned wheel counter contains all wheel movements accumulated since the last call to INT 33/AX=0003h, INT 33/AX=0005h/BX=-1 or INT 33/AX=0006h/BX=-1 positive value of wheel counter means downward wheel movement this call clears the wheel movement counter ---------------------------------------------------
