+It is also possible to use this interface type to connect via other programs
+or hardware devices that expose a KISS interface on a TCP port, for example
+software-based soundmodems. To do this, use the ``kiss_framing`` option:
+
+.. code::
+
+  # Here's an example of a TCP Client interface that connects
+  # to a software TNC soundmodem on a KISS over TCP port.
+
+  [[TCP KISS Interface]]
+    type = TCPClientInterface
+    interface_enabled = True
+    outgoing = True
+    kiss_framing = True
+    target_host = 127.0.0.1
+    target_port = 8001
+
+**Caution!** Only use the KISS framing option when connecting to external devices
+and programs like soundmodems and similar over TCP. When using the
+``TCPClientInterface`` in conjunction with the ``TCPServerInterface`` you should
+never enable ``kiss_framing``, since this will disable internal reliability and
+recovery mechanisms that greatly improves performance over unreliable and
+intermittent TCP links.
