There are 2 buffers (RX one and TX one, both of 'reasonable' size)
(it's the effing echo-server, nothing more)

* print content of RX-buffer, ommiting terminating '\n' ('\n' is 
the 'end of request') to (log/journal file)/stdout/

* ouptut received 'message' back to client, _with_ terminating 
'\n'
