Either:

    Look for a success message and change the sense of the test.

    Run the remote command in verbose mode.

    Wrap the remote command in something that does output a     reasonable message (or re-write it to do so if you have     any control).

If the command has neither verbose mode nor any useful messages by default then give its programmer 30 lashes w/ a wet noodle for designing undecipherable code.
