  1. README file for directory ./clockstuff of the NTP Version 4 distribution
  2. This directory contains the sources for utility programs designed to
  3. support radio clocks. The chutest.c and clktest.c are desgined to
  4. test the chu_clk and tty_clk line disciplines and STREAMS modules in
  5. the ../kernel directory.
  6. These files have been modified to work with either the line disciplines
  7. or the STREAMS modules. Be sure to define -DSTREAM if appropriate.
  8. These are random bits of things written to help with clocks. You can
  9. make things in here by typing one or more of:
  10. make propdelay (or `make')
  11. make chutest
  12. make clktest
  13. Propdelay computes high frequency propagation delays, given the
  14. longitude and latitude of the transmitter and receiver. Use
  15. this for WWV/H and CHU. Don't use it for WWVB (the computation
  16. is easier for that).
  17. Chutest can be used to input and process data from a CHU modem
  18. attached to a serial port. It will use the CHU line discipline
  19. (if installed), or raw mode otherwise. This was used to test
  20. out the initial reduction algorithms, and may not be up to date.
  21. Clktest can be used to test the clock line discipline (CLKLDISC,
  22. it must be available), and to take a look at radio clocks attached to a
  23. serial port.
