Ok. Short summary (on mxser, moxa is different):

- multiple board support is broken
- driver blows up on illegal device minor numbers opened
- no security checks whatsoever on internal array overflows
- Completely broken port-number setup
- No visible NULL-pointer checks regarding dynamic structures

It looks like original taiwanese work: it is usable, but there are so
many dead ends in this code, you won't believe - and I did only look
some few minutes on it.

It desperately needs cleanup.

Listen Tim, if you want to do it, I can help you. But keep in mind, I
have no hardware. So I am probably not the right guy for maintenance.
If you do not feel comfortable, I will try it.
