--- Comment #2 from Rick Stanback rick@tripletry.com --- I know it worked fine in wine 4.8 but not much more than that. I am not sure if the problem is wineserver as I don't really know where the com port code is.
I can try and go back to wine4.8? I don't really build wine from source so not sure how to do that level of regression. I could try to build a newer version if there is one?
