I see...I think we have a very similar setup, and I see how you init your ports. Although I'm not sure if this is suitable for me, since editing the ns16550-files to support/init an external COM-chip is not a really clean/nice implementation.
I'm not sure if there is any way to implement this in a nice way. But I will let you know if we find something ;) thx for your help!
