"""\
Test the ability to get and set the settings with a dictionary.
Part of pyserial (http://pyserial.sf.net) (C)2002 cliechti@gmx.net
Intended to be run on different platforms, to ensure portability of
the code.
These tests open a serial port and change all the settings on the fly.
If the port is really correctly configured cannot be determined - that
would require external hardware or a null modem cable and an other
serial port library... Thus it mainly tests that all features are
correctly implemented and that the interface does what it should.
