You can catch this signal using a signal handler:

procedure term(sig :longint);cdecl;
begin
Writeln('Interrupt caught');
Halt;
end;
Note that in real programs, you should never call writeln (or pretty
much any other RTL function) from a signal handler, as many routines
are not re-intrant (and there is no documentation regarding which
routines are safe to call from signal handlers and which aren't).
