Thanks for this, the idea of using a serial port to generate the DCF77 data in WWVB3.C is most ingenious. We may actually have to do this as the braindead modem that were were using for initial development has a timing resolution of 18.461ms, so impossible to do times that are multiples of 100ms :) Oh well, if engineering was easy, everyone would do it.
