how to test the example SerialDisplayDriver?

With a super obscure little LED screen that can be programmed to display things via serial port. The example is just there as another thing to look at. You won’t really be able to test it…

I just want to see how to write a OPC-UA Serial drive,so if there is a program that can run,I will see the sourse code to see how it works , but when I test the SerialDisplay modl by Add the devise ,there is a text field let me fill :¿SerialDisplayDriver.Categories.SerialPortCategory.Name? how can I do?
