Hallo Reinhold,

At a baud rate of 50, one character (start bit, 8 data bits, stop bit)
at the serial
interface has a duration of 0.2 sec.

The 'pips' that DCF77 transmits have a duration of either 0.1sec or
0.2sec, and
therefore appear as characters either with all bits set or with the
first four data bits set.

If you try to set to serial interface to a baud rate other than 50, you
would have to do
significant re-engineering of the bit decoding algorithms. You might
want to look at
parseutil/dcfd.c, lines 512ff, for more information about how it's
