This is a small program written in plain C for Linux to control my LG TV from the command line. It has been tested under Ubuntu 16.04 Xenial Xerus only.
Run make in the folder. No really, that's it.
Run ./lgtv --device=<device> [OPTIONS] [COMMAND]. If you do not get any output from this command, it means no TV is connected to the selected serial port. If a compatible TV is connected, you should see a X 01 NGSSx reply, where SS is the Set ID (in Hexadecimal) of your television
