1## template:jinja 2 3## 4## Radio and modem clocks by convention have addresses in the 5## form 127.127.t.u, where t is the clock type and u is a unit 6## number in the range 0-3. 7## 8## Most of these clocks require support in the form of a 9## serial port or special bus peripheral. The particular 10## device is normally specified by adding a soft link 11## /dev/device-u to the particular hardware device involved, 12## where u correspond to the unit number above. 13## 14## Generic DCF77 clock on serial port (Conrad DCF77) 15## Address: 127.127.8.u 16## Serial Port: /dev/refclock-u 17## 18## (create soft link /dev/refclock-0 to the particular ttyS?) 19## 20# server 127.127.8.0 mode 5 prefer 21 22## 23## Undisciplined Local Clock.
