My pigpiopigpio library supports reading and writing 9-bit serial data. It uses bit banging so you can use any available GPIO.

If I remember correctly any speeds of 19.2 kbps or slower were pretty stable.

What bits per second do you need?

Reading (CC, PythonPython) is slightly easier than writing (CC, PythonPython).
