## 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?)
