Hello!

I have buy an Tobit LAN!Time DCF-77 serial port receiver but this device
will not work with ntp as referenc clock.

I have found this site http://www.woody.ch/tobit_ntp.php and have the same
configuration.

# Local Clock
server 127.127.8.0 mode 16 prefer

The symlink have i set.

Wenn i start the ntpd the LED on the device beginns flashing. But the ntpd
does not receive any time data.

The Clock works correctly on windows with the programm DCF77_32.exe provided
on this site: http://www.rrs-web.net/in3her/dcf77_32.html

I use Debian Lenny and ntpd 4.2.4p4

I have test the clock with mode 14 and mode 5 but nothing works.
