-"""Some tests for the serial module.
-Part of pyserial (http://pyserial.sf.net) (C)2002-2003 cliechti@gmx.net
-
-Intended to be run on different platforms, to ensure portability of
-the code.
-
-For all these tests a simple hardware is required.
-Loopback HW adapter:
-Shortcut these pin pairs:
- TX <-> RX
- RTS <-> CTS
- DTR <-> DSR
-
-On a 9 pole DSUB these are the pins (2-3) (4-6) (7-8)
