Some tests for the serial module.
|
|
Part of pyserial (http://pyserial.sf.net) (C)2001-2009 cliechti@gmx.net
|
|
|
|
Intended to be run on different platforms, to ensure portability of
|
|
the code.
|
|
|
|
This modules contains test for the interaction between Serial and the io
|
|
library. This only works on Python 2.6+ that introduced the io library.
|
|
|
|
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)
