The terminal using cat and echo cannot detect response. I think it is possible to open one terminal and use cat so it will keep polling for and reply. And use echo on the other terminal. Cutecom seems to be good to try. Try also putty and minocom. See if any works. Before that, make sure the settings are correct especially the baud rates.
