Yes, they are responsive. Here is the current reply: Dear Bruce,   I've got updated news from the R&D Div., they are testing the latest beta version of the driver for all the Moxa cards, only they can not provide me with a precise schedule. Your case will be remaining open until it is resolved, I will also keep you update with the information.
