    I tried and it works well.
    In case of problems, here is:

      Hello,
      well, I'm also working on data transfer between a PIC 16F877 via a parallel port. I've encountered a lot of problems, so if you could help me, that would be great.

      Thank you in advance.

    Thank you Jeff,
    but it doesn't give me much
    actually, the information coming from the parallel port should be entered into an "edit": "edit1.text" for example.
