This is now written up here - comments and corrections warmly invited:
By using /both/ the kernel-mode driver, /and/ enabling interpolation,
averaged jitter on this system has been reduced from over 1.5 milliseconds
to under 40 microseconds. Not often you get an almost forty-times
improvement for a couple of hours work!
My thanks to Dave Hart for his Windows support, the modified serial
driver, and for discovering how to use unsigned drivers!
