Int 16/AH=11h

KEYBOARD - CHECK FOR ENHANCED KEYSTROKE (enh kbd support only)

AH = 11h

Return:
ZF set if no keystroke available ZF clear if keystroke available AH = BIOS scan code AL = ASCII character

Notes: If a keystroke is available, it is not removed from the keyboard buffer. Unlike AH=01h, this function does not discard extended keystrokes. Some versions of the IBM BIOS Technical Reference erroneously report that CF is returned instead of ZF. INT 16/AH=09h can be used to determine whether this function is supported, but only on later model PS/2s
