I was troubled by the reading/writing from parallel port on win2000 for a long time. I had made my programs work on win2000/OLD PC, but i failed with the same programs on win2000/new PC. I tried with the method from the forum, that is, install accessHW and other method from my colleagues. Allways failed. I have to return to an old pc, it work! I think not only win2000/winxp will influence parallel port work, but also pc hardware. My new PC is Dell's GX260SMT with p4 2.4G. Dell's FAE told me that i can not install win98 on the pc due to some limitation of mainboard. Who met the smae issue as mine? How to fix it? Thanks for any help.
