Support for my serially attached DCF77 receiver (server 127.127.8.0
mode 14) reference clock is also broken.

ntpd logs the supposedly received time stamp every minute:

Aug 24 13:14:20 lorvorc ntpd[32943]: parse: convert_rawdcf: parity check FAILED for "--#--#-#---##--R-D--S--4812-p-2----P----1-1-4--48-12-812--P__"
Aug 24 13:15:22 lorvorc ntpd[32943]: parse: convert_rawdcf: parity check FAILED for "##-#-#--###--#-R--M-s1248---P----1-p--4--2--4----11-----4-p?_"

However, this is random garbage.  I've truss(1)ed ntpd and the bits
it actually reads from the serial port are correct.  Somehow they
don't make it into the time stamp.
