RS232 on TV and Freeview Sat box. What is this serial port for?

  Batch 13:44 13 Feb 07

Dunno about the TV. But my Humax Freeview STB has serial connection which can be used for uploading firmware upgrades from PC (after first downloading from Internet). Although the upgrades are available over the air, they are available sooner off the Internet.

For this to work, one requires (for my box) what is known as a Null Modem Cable (and, of course, a serial connection on your PC). Cables avaialble on ebay, maplin etc.

If you haven't got a serial connection on your PC, you can get a USB to serial adapter.

It should all be described in your manual.

Maybe the TV can take firmware upgrades in a similar way.

Yes they both are upgradable, over the air. So it looks like that is what they are for. Will tick this
