I just installed the beta2 pdaxrom am my C1000 and now I try to ust my Targus IR-Keyboard

XirKD works fine, but how can I use the german special letters like ÜÄÖ

zkbdd don't work.
I can start
zkbdd -t targus -d
and I see all the codes comes from the keyboard, but when I start without -d I can't type any letter

What did I wrong with zkbdd?
