Nice find but you made one mistake. RS232 mode needs to be set to Debug :) Setting UART to ON is enough to enable FULL exlink on headphone jack :) You will see HUGE difference in a size of output :D When set to UART exlink (on ANY port) gives you ONLY basic message. Anyway once again good find.
I'm aware of the difference between Debug and Uart. Maybe I wasn't to precise when writing my post.
But anyway I've found out that some commands give you also current TV status. For example the 08,22,f0,01,00,00,E5 gives you the current volume level. If anybody's interested I can share more commands and findings.

You can post people will check if they find something interesting :)
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on http://ctrlv.it/ Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!

...exlink works on my h6640 tv through the audio out (headphones) jack. All you need to do is enable uart and change the rs232 mode to uart in the service menu. Now I can control my tv through rs232.
Thanks for your awesome work guys!
Hello rexio8, thanks for sharing this information. I'm a little bit confused regarding "enable uart", as this is mentioned only 1 other time in this forum, and it's also not in the wiki:
Service Menu -> Options -> Sub Options : Set: Enable UART - ON

Is this the option which you changed?
What happens with the audio signal from the headphones port? Do you still hear audio when you connect normal earphones?

Joing this thread a little late.

I have made an 3.5mm ExLink cable, and using a RS232 serial-usb adapter (FTDI chip).

I am able to see the debug output when RS232 mode set to debug and I connect using the 115200 baud rate.

I am having difficultly sending any commands, I’m using Minicom to connect.

Can someone just explain so I need to use Rs232: UART or Debug. And if I use UART is it 115200 or 9600 baud rate.

Finally when sending commands do I need to send the console unlock code. When using Minicom and the console unlock code on the wiki I don’t get any response.

Any help would be greatly appreciated
