- README file for directory ./clockstuff of the NTP Version 4 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.
