I'm trying to flush the keyboard buffer, but I'm not succeeding. My program displays a message for the user to read, and the user has to press space for the program to erase the message and proceed. The problem is that if the user presses space before the message is displayed, the message will show for a fraction of a second, and the program will erase it and proceed. I've been trying INT 16h, and MOV IN, 60h, and no success so far... Help, please!
FLUSH_KB_BUFFER:
MOV AH, 1h ;CHECK IF KEY IS AVAILABLE
INT 16h
JZ PRESS_SPACE_
MOV AH, 0h ;READ PRESSED KEY
INT 16h
JMP FLUSH_KB_BUFFER
PRESS_SPACE_:
MOV AH, 0h
INT 16h
CMP AH, KB_SPACE
JNE PRESS_SPACE_
