Use twisted.conch.manhole.ManholeInterpreter.  Here's its docstring:

class ManholeInterpreter(code.InteractiveInterpreter):
    """Interactive Interpreter with special output and Deferred support.

    Aside from the features provided by L{code.InteractiveInterpreter}, this
    class captures sys.stdout output and redirects it to the appropriate
    location (the Manhole protocol instance).  It also treats Deferreds
    which reach the top-level specially: each is formatted to the user with
    a unique identifier and a new callback and errback added to it, each of
    which will format the unique identifier and the result with which the
    Deferred fires and then pass it on to the next participant in the
    callback chain.
    """
