Hi Wolfram,

sorry for the delay, but I'm very busy these days.

I noticed that some of your patches revert the changes made by the previous patches in the
same series. So I would have preferred having only one patch with the whole changes wrt to
the mainline.

However, I've understood that some of those patches come from a previous submission that you
preferred to not touch. And I can apply the whole series to check what are the actual changes,
so its' fine.

The RS485 part looks right.

I had a superficial look also at the rest of the code, and its seems OK too. But, honestly, I couldn't
find the time to read it carefully.

Best regards,

Claudio
