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.
