I have just compiled and tested gscanbus. It works fine. I had the source somewhere on my drive for 2 months, but I did not spent any time for compiling it. Thank you for your help. I think all the anwers for my questions will be in the source of gscanbus. I will try to work for a simple utility and give it for testing as soon as possible.
