There are as far as I know two ways of doing this. The easiest way
is to use the signal(3) call, or maybe the underlying system
call, and tell it to ignore SIGSUSP, SIGINTR, SIGTERM, and a few others.
Or if you prefer, call one of your own routines.

The other way is to manupulate the terminal handler, which sends the
above mentioned signals. By calling ioctl(), you can set a lot of things,
which I leave you to discover for yourself.

Send a mail if it doesn't work, and I'll see what I can do to help you.
