Ich habe das doch installiert : pyserial-2.5.win32.exe
Und hier eine Demo, da kommt die gleiche Meldung.

"""\
Some tests for the serial module.
Part of pyserial (http://pyserial.sf.net) (C)2010 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)
