ntp 4.2.6p5

    1: README file for directory ./clockstuff of the NTP Version 4 distribution
    2: 
    3: This directory contains the sources for utility programs designed to
    4: support radio clocks. The chutest.c and clktest.c are desgined to
    5: test the chu_clk and tty_clk line disciplines and STREAMS modules in
    6: the ../kernel directory.
    7: 
    8: These files have been modified to work with either the line disciplines
    9: or the STREAMS modules. Be sure to define -DSTREAM if appropriate.
   10: 
   11: These are random bits of things written to help with clocks.  You can
   12: make things in here by typing one or more of:
   13: 
   14: 	make propdelay (or `make')
   15: 	make chutest
   16: 	make clktest
   17: 
   18: Propdelay computes high frequency propagation delays, given the
   19: longitude and latitude of the transmitter and receiver.  Use
   20: this for WWV/H and CHU.  Don't use it for WWVB (the computation
   21: is easier for that).
   22: 
   23: Chutest can be used to input and process data from a CHU modem
   24: attached to a serial port.  It will use the CHU line discipline
   25: (if installed), or raw mode otherwise.  This was used to test
   26: out the initial reduction algorithms, and may not be up to date.
   27: 
   28: Clktest can be used to test the clock line discipline (CLKLDISC,
   29: it must be available), and to take a look at radio clocks attached to a
   30: serial port.
