A monomeserial implementation in Python. Uses a Windows-only USB/Serial library but that should be pretty easy to replace. This used to serve a purpose for me but since serialosc it should no longer be needed.
The last time I used it, I used Python 2.6.5 and PyUSB 1.6. Newer versions should probably be fine.
PyUSB: http://www.bleyer.org/pyusb/
Once that is installed just run monomeserial.py. If you want to configure it (cable orientation, offset, etc.) then you'll have to send it some OSC messages. The client.py file contains a few examples on how to do this.
