Do you mean ethernet, or do you mean cat-5/6? Years ago, I put a cat-5 loom in from the first floor to the basement of our office - about 40m of cable iirc. Then the office manager asked me "how do I control our telephone exchange on the first floor from my pc in the basement. I simply ran a cat-5 extension from each end of the loom into serial ports on the PC and the exchange. "serial to cat-5" converters were (and still are?) dirt cheap.
