Gee, nice diagrams.  If done earlier, it might have saved a thousand words.

Ready for the next question?  Why an SAK like ^K?  Why not just have loss
of DTR be the attention signal?  You're going to blow off the previous
session anyway, might as well let terminal poweroff automatically serve
as your SAK.  (Yes, I know you have to wire and configure things correctly,
but that sort of argument applies to any scheme.)
