You are correct. I suppose serial data is more like a clocked stream than packets. Perhaps I was thinking of TDMA instead of TDMS. Flicking bits is easy indeed,

You are correct. I suppose serial data is more like a clocked stream than packets. Perhaps I was thinking of TDMA instead of TDMS. Flicking bits is easy indeed, which should be mostly mitigated with the requirements on the conductor and shielding.
