It figures.  ^C handling is one of the dark corners of DOS emulators.

Accidentally, does CTRL-Break call your handler on OS/2?

The display of ^C is normal DOS behavior.  If you want to avoid that,
make your handler gobble the character in the keyboard buffer, if
there is any (CTRL-Break does NOT leave any characters there, but does
generate SIGINT).
