Froggy, a quick test you could do if you have a multimeter avaible: Write a simple loop that drive the TX line HIGH for 5 sec and low for 5 sec. Test at the K-line output of the mc33290 or at the db9 connector. You signal might be reverse for a reason I cant explain right now... mine is like that..
