My LG TV can be controlled over a RS232 port! The Problem is that I don't have any serial devices to test it.

So my question is, can I do it with a rollover cable(RJ45 <--> D9)? I mean can I plug it into my Ethernetcard, start putty and communicate to my TV?

My OS is Ubuntu so if there a specific things I can do it would be really great

Thanks for your help

RS232 amd ethernet are completely different on physical level. Actually, on any other level too. So no, you can't just connect it to Ethernet port. But if it's a smart TV, maybe it has actually Ethernet. In fact i can't think of any reason to put RS232 on TV and not to pu Ethernet.
