[realin]

yeah i know about that codeproject post, i refered to that only making this whole thing there after..

but my parallel port is gone now.. cant do it much till i get a new one that fits to PCI slot

Well guys finally my parallel port is busted adn i have decided not to change the circuit and leave it as it is..
becuase otherwise i would messs something else, but still your last recommendation is what i am looking forward adn if any one can give me link for sending interrupt through USB..

thanks
