Ok.

Well, presumably this is code you supply somehow -- the free
implementations don't provide com.sun.*.  If this isn't your code or
somehow freely available, then perhaps the problem is that you're
relying on undocumented APIs.  (I'm not a javax.comm expert so I don't
know.)

If you have all this code in some form you can use, and it still isn't
working, then perhaps the problem is that java.library.path isn't
implemented in the version of gcj you are using.  What version is it?

Offhand, I have no idea.  FWIW the free version of javax.comm I know
of is RXTX: http://www.rxtx.org/.  Maybe that is helpful.
