Hi David,
many thanks for your reply.
At first the answer to your question:
I copied the two files (librxtxSerial.so and the RXTXcomm.jar) directly into the ~/arduino-0018/lib-directory.
Maybe you also read the other thread, which I started yesterday, some hours after having started this thread. So, obviously, I already have problems with my actual configuration. But before starting to fix the problem according to your solution, could you please answer the following questions ? (just for a better understanding of the things that happen):
1 Does your suggestion mean, that I shouldn't worry about the different version-numbers of the java-libs ? (Or in other words: shall I switch back to the original rxtx-libs, as they are content of the current arduino-IDE ?)
2 Why is the 13Pin-LED already blinking although I haven't uploaded anything yet ? The Pin13-LED started to blink immediately when I connected the (brandnew) Duemilanove the first time after unpacking it. Is this OK, or does the blinking LED mean that anything is wrong with the board ?
Greetings from good old Germany, Rafa
