10 * A backend which can send and receive the data somewhere.
12 When using the peripheral you select which backend is used for each UART instance
14 If no backend is enabled, that UART instance is disconnected: whatever is sent is dropped, and
37  * The loopback backend
38  * The FIFO backend
39  * The PTY backend
41 #### The Loopback backend
43 This backend just connects an instance Tx to its Rx, including the RTS and CTS signals.
46 #### The FIFO backend
48 This backend can connect two instances of these UART models to each other.
52 Therefore you cannot connect this backend to a console, or real devices.
54 You enable this backend for each instance using command line parameters, by specifying
57 The backend will automatically create and delete the FIFOs on its own.
61 The backend will also realize about a possible abrupt disconnect from the other side.
63 In case of a graceful disconnect from the other side, the backend will, by default, also
65 just disconnect the backend and continue running.
67 For performance reasons, the backend does not react immediately to a CTS/RTS pin toggle from the
74 the backend will print a warning for each received byte, but the ERRORSRC register in the UART
83 Note that you can also use the loopback backend when connecting a single instance in loopback,
87   Do not connect both devices which are connected thru the UART FIFO backend to the Physical layer
94 #### The PTY backend
96 With this backend you can connect a UART to a Linux pseudoterminal. A new pseudoterminal will be
97 created for each UART for which this backend is enabled.<br>
