I did not change anything, I even did not set anything special 
back with FreeBSD 7.4 during the setup of ntpd for the DCF77 
mouseCLOCK.

Here the settings of the serial (sorry for the line wrapping):

Is there anything I can do to debug?


PS: No need to use "reply all", reply only to the list is 
perfect, as I do filter e-mails based on the "List-Id" header line.
