    Hi again;

    I have successfully taken code from your examples and written a program that
    makes the output lines of the printer port go hi/low as desired and toggle a
    relay.

    Now, I have two more problems:

    Gora - what you said is correct; I have to be root to get your program to
    work. Otherwise, I get a "segmentation fault" error. How can I get around
    this?

    I need to have Apache (which runs as wwwrun) execute this code in my cgi-bin
    directory. I'm setting this up so when someone clicks on a bar
    on the webpage, it pulls in a relay.

    Thanks again for your help.
