I have two RCA sat TV receivers. The one in the living room is part of a TIVO system. The Sony TIVO controls the sat receiver through the RJ-type "low-speed data port" on the back of the receiver.
I would like to control my bedroom sat receiver with a PC through its low speed port. But, several hours of search engine time has netted a lot of info about the illegal "test card" and nothing about the specs on the low-speed port.
Anybody have any ideas?
