+------------------------------
+
+Usage
+~~~~~
+
+.. code-block:: bash
+
+    platformio serialports monitor [OPTIONS]
+
+
+Description
+~~~~~~~~~~~
+
+This is a console application that provides a small terminal
+application. It is based on `Miniterm <http://pyserial.sourceforge.net/examples.html#miniterm>`_
+and itself does not implement any terminal features such
+as *VT102* compatibility. However it inherits these features from the terminal
+it is run. For example on GNU/Linux running from an *xterm* it will support the
+escape sequences of the *xterm*. On *Windows* the typical console window is dumb
+and does not support any escapes. When *ANSI.sys* is loaded it supports some
+escapes.
+
+To control *monitor* please use these "hot keys":
+
+* ``Ctrl+]`` Quit
+* ``Ctrl+T`` Menu
+* ``Ctrl+T followed by Ctrl+H`` Help
+
+Options
+~~~~~~~
+
+.. option::
+    -p, --port
+
+Port, a number or a device name
+
+.. option::
+    -b, --baud
+
+Set baud rate, default ``9600``
+
+.. option::
+    --parity
+
+Set parity (*None, Even, Odd, Space, Mark*), one of
+[``N``, ``E``, ``O``, ``S``, ``M``], default ``N``
