Wire over ethernet
PlainName:
You can get a pair of network adapters where you feed, say, serial data in one end and it comes out the other as if it were hard wired rather than traversing a network. I am looking to do the same but for ad-hoc digital or analog signals. Essentially, this is to be used where UTP was used to connect some stuff and that's now been co-opted to run network data instead - the original functionally now needs to run over virtual wires.
Before I start down the rabbit hole this is bound to turn into, is there an existing product that does this (or something very close)? A search didn't turn up anything but that might well be because I don't know what it might be called.

Please make your requirements right. Serial data is not the same as analog, or any random digital signal.
With a pair of Ethernet MCUs, you could easily send raw data over UDP, it's the simplest protocol I know.

I would probably just use something like a Raspberry Pi as the network device, then use the GPIO pins and some Python code to send your analog or digital signal over Ethernet.

I was using the serial over ethernet kit as an example, to illustrate the kind of setup I have in mind. But I did say it was for ad-hoc stuff - can't say exactly what because I don't know right now. Think of something you'd join wire a bit of wire, and it could be that.

Yes, that's the idea, although I wouldn't use a Pi nor Python :)
So what I am asking is whether that kind of thing already exists, or if I need to actually make it.
