README file for directory ./clockstuff of the NTP Version 3 distribution
|
||
|
|
|
||
|
|
This directory contains the sources for utility programs designed to
|
||
|
|
support radio clocks. The chutest.c and clktest.c are desgined to
|
||
|
|
test the chu_clk and tty_clk line disciplines and STREAMS modules in
|
||
|
|
the ../kernel directory.
|
||
|
|
|
||
|
|
These files have been modified to work with either the line disciplines
|
||
|
|
or the STREAMS modules. Be sure to define -DSTREAM if appropriate.
|
||
|
|
|
||
|
|
These are random bits of things written to help with clocks. You can
|
||
|
|
make things in here by typing one or more of:
|
||
|
|
|
||
|
|
make propdelay (or `make')
|
||
|
|
make chutest
|
||
|
|
make clktest
|
||
|
|
|
||
|
|
Propdelay computes high frequency propagation delays, given the
|
||
|
|
longitude and latitude of the transmitter and receiver. Use
|
||
|
|
this for WWV/H and CHU. Don't use it for WWVB (the computation
|
||
|
|
is easier for that).
|
||
|
|
|
||
|
|
Chutest can be used to input and process data from a CHU modem
|
||
|
|
attached to a serial port. It will use the CHU line discipline
|
||
|
|
(if installed), or raw mode otherwise. This was used to test
|
||
|
|
out the initial reduction algorithms, and may not be up to date.
|
||
|
|
|
||
|
|
Clktest can be used to test the clock line discipline (CLKLDISC,
|
||
|
|
it must be available), and to take a look at radio clocks attached to a
|
||
|
|
serial port.
