I have netrunner2 beta 18 which seems to still the latest available for download from http://mysticbbs.com/downloads.html. Is there some other download location for beta 19?

Right. So upper left should be "!!", not "))" as is being sent by Netrunner2 beta 18.

Yup, that jives with xterm and the "X10 compatibilityi mode" in the relevant docs I've located.

Which is why the SGR-extended encoding is preferred. You can combine SGR-extended encoding (esc[?1006h) with the other mouse protocol modes.

In that doc I referenced, that mode is called "Normal tracking mode". In that mode, the X and Y coordinates should be encoded as in the X10 mode we talked about above.

Yup, noticed that. It's different than the standards, but works.
