Not on my p9p 9term:

% stty
speed 38400 baud; line = 0;
intr = ^?; erase = ^H;
-brkint -imaxbel
-onlcr onocr
% cat
^?
% stty intr '^C'
% cat
^C
% cat
<Press C-c, RET here>
^C

I pressed DEL twice, and after that C-c.  The second DEL sends C-c, see
/opt/plan9/src/cmd/9term/9term.c:441:winterrupt(Window *w)
