Thanks for helping. But since I am using LabVIEW 6.1 I cannot open your VI which is written in LabVIEW 7. Please convert it to 6.1 or send back a picture of your code.
(Under Windows 9x: Open the diagram, press Alt+Print (Druck in Germany, next to F12) paste the picture in MS Paint, save it as JPG or BMP or whatever and send it to the Forum.) Arno
