I had the same issue until I switched to a real RS422 converter instead of just using the rs232 types and hoping for luck. Also, as there are both positive and negative terminals on emit and receive, I think switching from one to the other kept it from hanging. But by then I had ordered the cheap RS422 converters and installed them anyway.
