Before making a custom cable to enable use of the TV's 3.5mm jack, I realized the TV also has multiple USB in ports and I have a USB to serial converter. I connected the converter to the URC RS232F cable on port 7. Anything I should know about doing this rather than utilizing the 3.5mm input? I've not yet gotten it to work but I've only barely started testing.
Don't. You'd need the TV to have & support a driver for whatever model of USB-RS-232, and also to NOT power down the USB ports when the TV is shut off.
