Store COM port in JSON or similar configuration file optionally
- I think it would be nice to not retype the COM port each time. The COM port depends on the current machine used, so I really don't want to hardcode it. A nice way would be to store it is a config file like a json file which is then not included by the version control. This could also be used to store other global variables which are only specified once on a machine (e.g. IP address and port for UDP)
- Python propably has libraries to generate these types of files
