    Windows through Windows 7 will operate a classic serial port
at 45 baud 5 bit just fine.  Here's the setup in Python:

self.ser = serial.Serial(port, baudrate=45, timeout=timeout,
                bytesize=serial.FIVEBITS,
                parity=serial.PARITY_NONE,
                stopbits=serial.STOPBITS_ONE_POINT_FIVE)

Windows 2000 through Windows 7 will work.  Linux doesn't
handle non-standard baud rates properly for historical
reasons (it didn't work on the PDP-11).
