[Rxtx] Not receiving 0xa characters

[Michael Erskine]

OK, to stem this madness I just ran some tests on RXTX-2.1-7 using
java.io.InputStream.read(byte[]) to collect bytes from a RXTXPort
SerialInputStream instance. I am reading and writing linefeeds with no
problem.

If somebody has a genuine issue with their data receive code just post
it here and I will show you exactly why it is broken.

Thankyouverymuch.
