   1 \section{General message format}
   2 Messages are delimited by newlines to make processing by line based devices
   3 more easy. Message exchanges have a \emph{Request} and \emph{Response} header.
   4 The \emph{Request} header means that the server is sending to the client. The
   5 \emph{Response} header means that the client is sending to the server. In some
   6 cases either the \emph{Request} or \emph{Response} is empty. This means that
   7 the message is not acknowledged or responded upon.
