So the correct combination, 5 bits with 1.5 stop bits, isn't supported in Python. 1 stop bit will not physically work on Baudot teletypes; the main camshaft doesn't come around fast enough. (Yes, there's an actual mechanical reason for 1.5 stop bits.) Requesting 2 stop bits at the Python level gets a reject at the Win32 level. (Not sure why Win32 doesn't allow that; extra stop bits just add delay, but don't hurt anything. But it's not supported.)
I forgot to add that what Windows allows depends on what the hardware (the serial chip) allows: the MSDN webpage mentions that the DCB struct configures the 8250. -- http://mail.python.org/mailman/listinfo/python-list
