parallel port interfacing using c

hi all

i want to capture the pulses coming on the parallel port from rotary encoders using C. for that i have written the code using C. even though it detects the signal, when i switch off the external circuit it still shows tht value. is thr any buffer or so which stores that value? ....

also how to activate ECP or EPP mode of parallel port since i will be getting 5000 pulses per second i may need to activate that?

    Care to be more precise with the question? The problem might just be with the way you have structured your program.
