The particular ## device is normally specified by adding a soft link ## /dev/device-u to the particular hardware device involved, ## where u correspond to the unit number above. ## ## Generic DCF77 clock on serial port (Conrad DCF77) ## Address: 127.127.8.u ## Serial Port: /dev/refclock-u ## ## (create soft link /dev/refclock-0 to the particular ttyS?) ## # server 127.127.8.0 mode 5 prefer ## ## Undisciplined Local Clock.
