 Left is only communication between the receiver modules and \name{queue-in}, and between \name{queue-out} and the transport modules. Data is exchanged using \unix\ pipes and a simple protocol. Figure \ref{fig:ipc-protocol} shows a state diagram for the protocol. Solid lines indicate client actions, dashed lines indicate server responses.

 \paragraph{Timing}
 One dialog consists of exactly three phases: connection attempt, envelope and header transfer, and transfer of the message body. The order is always the same. The three phases are all initiated by the client process; after each phase the server process sends a success or error reply. Timeouts for each phase need to be implemented.

 The client indicates the end of each data transfer with a special terminator sequence. The appearance of this terminator sequence tells the server process that the data transfer is complete and makes the server send a reply. The server process takes responsibility of the data in sending a success reply. A failure reply immediately stops the dialog and resets both client and server to the state before the connection attempt.

 \paragraph{Syntax}
 Data transfer is done by sending plain text data. \name{Line Feed}---the native line separator on \unix---is used as line separator. The terminator sequence used to indicate the end of the data transfer is the \NAME{ASCII} \name{null} character (`\texttt{\textbackslash0}'). Replies are one-digit numbers with `\texttt{0}' meaning success and any other number (`\texttt{1}'--`\texttt{9}') indicate failure.
