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.
