Oh, heh. Well, if the hardware is non-standard, then one hack is as good as another. Never mind what I said, this is actually pretty elegant. Short of putting a microcontroller on your board, I have no suggestions. :) As far as doing control line stuff from userspace, though, this is possible under Linux (and maybe elsewhere -- I'm not sure how portable these APIs are) using the TIOCMGET/TIOCMSET ioctl's with the TIOCM_RTS and TIOCM_DTR flags. Since you are using them for synchronous I/O, though, you will have to poll them to watch for changes on the clock line. Obvoiusly polling hardware from userspace is a recipe for disaster. And a suggestion for your site: could you list sources and part numbers and sources for the components? The sliders in particular (with colored knobs, even) look really useful for throttles, and I haven't seen that kind of thing before.
