The driver for Linux works fine, but you couldn`t use rs422 yet. For example when you are using Windows OS it suppose to be installed a configuration program. I`v tested three different situations:

- RS-422 works fine on Windows 10 with installed configuration utility on board.
- I`v supposed that if the Edgeport was configured once and properties was saved you could use it at another OS like Linux. But not.
- Using Edgeport on Windows 10 but without installed configuration utility made the same result as on the Linux. Com ports were visible but didn`t work.

The question is How to configure Linux to make it understand RS-422? Are there analog to configuration utility for Unix systems?
