list the serial devices attached to my Linux/Windows system?
------------------------------------------------------------
You can do it by running::
$ python3 -m serial.tools.list_ports -v
It will give you the ``/dev/ttyUSBxx`` (or the ``COMxx`` for Windows) device
names.
The ``hwid:`` field gives you the string you can pass via the ``hwgrep://``
feature of pyserial
`serial_for_url() <http://pyserial.sourceforge.net/pyserial_api.html#serial.serial_for_url>`_
in order to open a serial device.
See the :ref:`TDC001 documentation <tdc001-controller-usage-example>` for an example of ``hwgrep://`` usage.
