RFC: registry keys of serial ports

[Stefan Leichter]

Hi,

i like to know what modifikations the attached patch needs to go into git.

More things need to be done in this area. I know of:
- more registry keys [1]
- remove the registry keys when a serial port disappears (USB)
- the links in the dosdevice directory needs to be created

Patches for the items above will be created, when the current patch went into 
git
