I think it depends on your TV - you'd be advised to at least post the  
model number.

My new TV (Sharp Aquos LC-42XD1E) also has one of these ports -  
apparently it conforms to the RS-232 spec, and the section of manual  
that covers it is quite comprehensive - see pages 34 & 35 of <http:// 

I've only had this TV about a week, so I can't yet comment any  
further on its serial port - it annoys me slightly that it seems to  
have a power off "control item", but not power on.
