It's a pre-allocated system signal.  The defines are in dos.i or dosextens.i.
You can use an exec function to poll the signal, SetSignal() is the one
you should use, I think, but you should check.

If you want to make ^C cause a kind of "interrupt," then you have to set-up
an exception handler.  I've never done, this, so some guru will have to help
there.
