RunRev lack of rs232 Com Ports !

Now days people have so many allocated ports in use !

Virtual Com Ports for usb and bluetooth etc , etc

I have 100's of requests for users to be able to select Com port 10 and
above.

So its not that we need to use 10's of RS232 Physical ports but need to
allocate
more than revs out dated 1 to 9.

It's seem strange that Rev's RS232 Core can handle 1-9 only , I'm sure it
would not be a
vast code change to increase ?

Best Regards
