From your description, you are doing the right thing. If your black tank was empty, and water was flowing into it, you should see water etc. in the clear connector very quickly.
From the sound, could you tell if water was running through your hose when connected to the flush system? If so, you'll have find out where it is going!
You could have a blockage in the black tank that would stop water flow. Shut off all water pressure, your trailer water pump, and open you toilet flush valve. With a flashlight, in MOST trailers you can look down into the bottom of the black tank. If you see water, then you may have a blockage in the black tank or its plumbing. If you see a tower of poo, then that's something you'll have to work on to remove.
