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.
