## Radio and modem clocks by convention have addresses in the
## form 127.127.t.u, where t is the clock type and u is a unit
## number in the range 0-3.
##
## Most of these clocks require support in the form of a
## serial port or special bus peripheral. 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. This is a fake driver intended for backup
## and when no outside source of synchronized time is available.
##
# server 127.127.1.0 # local clock (LCL)
# fudge 127.127.1.0 stratum 10 # LCL is unsynchronized
##
## Add external Servers using
## # rcntpd addserver
## The servers will only be added to the currently running instance, not
## to /etc/ntp.conf.
