DTV Converter box with RS-232 (Tivax RS-232)

[politics123]

Hi --

So, I have one of the 35 million analog TVs (and happen to like it), so I've been shopping for DTV converter boxes. The Tivax one includes an RS-232 port, so I'm wondering whether anyone knows what can be controlled through it.

Thanks!
