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.

Best Regards,

Stephen Lin / Technical Support Engineer
