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.

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. + |
