Serial over Ethernet with HA (piefed.zip)

I just picked up a 4K commercial display to upgrade my TV for cheap. It has an RS232C port on the back for control, and Home Assistant has a native integration to control it via a local Linux tty. The hitch is that my Home Assistant server is located in a spot not near the television, and running physical serial line to it would be inconvenient. But, since I have a Raspberry Pi connected as the streaming media box, I should be able to plug a USB adapter into it and route the serial data over the network, right?

Is there a a good way to do this in HAOS?

Thanks! I see now that HA documentation just assumes that one knows that one can use the URL schema to specify the "port, " without saying so. iYKYK, I guess.
