 \subsection{Communication}

+The communication to and fro a device runs via a single \gls{SDS}. Every
+device has a specific resource that is used to connect to the device. The
+current system supports connecting devices via a serial connection and via a
+\gls{TCP} connection. Every device has the type \CI{MTaskDevice} and which
+is listed in Listing~\ref{lst:mtaskdevice}. When a device is added a background
+task is started that runs the \CI{synFun}. The \CI{synFun} is the task that
+synchronizes the channel \gls{SDS} with the actual device. For the \gls{TCP}
+device this is a simple \CI{tcpconnect}. The \CI{TaskId} of the background task
+is saved to be able to stop the task in the future. When the task is unable to
+connect it will set the \CI{deviceError} field to notify the user.
