At my previous job, I worked on RS485 and Modbus protocol. At my current job, we use RS485 for communicating between Power-over-Ethernet “smart building” controllers. RS485 is also used for DMX lighting, which I also have worked with.

I have found some of these cheap USB-RS485 have issues working with DMX (which may explain why DMX interfaces are so stupidly expensive).

You are suggesting using something like RS485 between CoCo and a PC with a cheap interface, rather than RS232?
