I'm not sure how well this would work with just one-way communication.

If you want to do it by setting up two-way communication, it would
probably be best to use ptys so that the Octave subprocess will think
it is actually talking to a terminal.

You might want to take a look at the way the octave-inf mode for Emacs
works.  Unfortunately, it might not be very simple duplicate all the
details of that since I think there is a lot of machinery provided by
the comint package.  However, I think the basic idea for handling the
prompt is to use a regexp to match the prompt.
