No problem. I should be able to modify it.

But the program I wrote myself isn't very user-friendly. I just change the source and run it in Borland C++ (for DOS) so you would have own Borland C++ and know a little bit about programming. If you want this program send me a mail ... and i will send you the program and the circuit i used. =================================================================== Kraft Bernhard aka.
