[Rxtx] RXTXCommDriver.registerSpecifiedPorts

[Trent Jarvi]

The best way is to post diff -uw reslts between the original and new files 
to the mail-list.  Keeping the changes to just want you are trying to do 
means there is a better chance people will be able to follow the changes 
and approve of them here.  One fix at a time facilitates others reading 
the changes.

If you post a few changes and people like them, we can give you write 
access to CVS.
