Once I found the datasheet for the RS-232 interface, I found the TX data was checking in but not out, and the circuitry that makes -V in the MAX3232 wasn't working. Replaced it * and all is well; Lady Heather is giving me nice maps of satellites passing by, and 2nsec excursions on a graph. So now my ancient Davis counter has a really really good timebase and I can tweak my ham rig to within a fraction of a cycle of right. Hardly a "time nuts" level of accuracy, but good enough! Thanks, all!
