If life was that simple ;-) Unfortunately that's not the issue. dns320l-daemon ( http://www.aboehler.at/hg/dns320l-daemon ) uses correct 115200 baud and doesn't work either. Since I can transmit, but can't receive, I will be first checking out mpp settings If that doesn't help, I guess it's git-bisect time.
