I noticed that we already have a File_InputAvailable() function in file.c
that could be used for polling, so I changed now the rs232 code to use
that, too, and dropped the thread code there now.
Not that this function uses select(), so I guess this still won't work
right on Windows... if someone really needs the rs232 code there, they have
to come up with an implementation of File_InputAvailable() for this OS (I
personally neither have a clue nor an installation to test this).
