Remote control a denon 2308 over the COM Port with RS-232.
Probably works for many other denon AVR's. For other commands see the attached PDF.
Default COM Port is /dev/ttyS0. You can change this in the py file.
Connect the Serial Port to the Denon RS-232 Port and run the python script:
python web.py
