    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.
