>Environment:
an atmosphere full of curses whenever it is relevant
>Description:
When wskbd is in raw mode, there is no key combination that enters ddb or triggers a crash dump.  All the logic to do that is either (a) in wskbd non-raw mode, or (b) in ttys to handle cnmagic.  So C-A-ESC and cnmagic are both broken.
>How-To-Repeat:
Hit C-A-ESC or the cnmagic sequence.

Observe no change.
>Fix:
Yes please!
