## FUNCTIONS
### serial_for_url
        Get an instance of the Serial class, depending on port/url. The port is not
        opened when the keyword parameter 'do_not_open' is true, by default it
        is. All other parameters are directly passed to the __init__ method when
        the port is instantiated.

        The list of package names that is searched for protocol handlers is kept in
        ``protocol_handler_packages``.

        e.g. we want to support a URL ``foobar://``. A module
        ``my_handlers.protocol_foobar`` is provided by the user. Then
        ``protocol_handler_packages.append("my_handlers")`` would extend the search
        path so that ``serial_for_url("foobar://"))`` would work.
