Hi Lars,

thanks for your advice; I used your recipe and got my DCF77 receiver up
and running :-)  BUT... the performance is very poor: more than 95% of
the time codes are unparseable! The same hardware with the same /etc/ntp.conf
works fine on my Linux box. There must be anything wrong with the serial
devices; I tried both, the /dev/tty* and /dev/cua*.

Any idea?
