Are you observing something different? > Thank you all for keeping an interest in this issue, Yes. I am using my laptop right now, and as it has gone to sleep, so the pen tablet does not work. When I "cat /dev/ttyS0" and move the pen on the tablet there is no output. I do not get the hang that I reported before. I apologize if that was erroneous but I definitely remember the laptop hanging. Anyway now, I can ^C and get out of the cat. I promise to run the tests with the new kernel and the debug lines that Dimitry asked for very soon. -- Marco
