154359SrobertoREADME file for directory ./clockstuff of the NTP Version 4 distribution 254359Sroberto 354359SrobertoThis directory contains the sources for utility programs designed to 454359Srobertosupport radio clocks. The chutest.c and clktest.c are desgined to 554359Srobertotest the chu_clk and tty_clk line disciplines and STREAMS modules in 654359Srobertothe ../kernel directory. 754359Sroberto 854359SrobertoThese files have been modified to work with either the line disciplines 954359Srobertoor the STREAMS modules. Be sure to define -DSTREAM if appropriate. 1054359Sroberto 1154359SrobertoThese are random bits of things written to help with clocks. You can 1254359Srobertomake things in here by typing one or more of: 1354359Sroberto 1454359Sroberto make propdelay (or `make') 1554359Sroberto make chutest 1654359Sroberto make clktest 1754359Sroberto 1854359SrobertoPropdelay computes high frequency propagation delays, given the 1954359Srobertolongitude and latitude of the transmitter and receiver. Use 2054359Srobertothis for WWV/H and CHU. Don't use it for WWVB (the computation 2154359Srobertois easier for that). 2254359Sroberto 2354359SrobertoChutest can be used to input and process data from a CHU modem 2454359Srobertoattached to a serial port. It will use the CHU line discipline 2554359Sroberto(if installed), or raw mode otherwise. This was used to test 2654359Srobertoout the initial reduction algorithms, and may not be up to date. 2754359Sroberto 2854359SrobertoClktest can be used to test the clock line discipline (CLKLDISC, 2954359Srobertoit must be available), and to take a look at radio clocks attached to a 3054359Srobertoserial port. 3154359Sroberto 32
