Our Samsung UA46C6200UM does not have a serial interface and while it 
has Ethernet it seems it's only good for firmware updates and DLNA, 
other versions with Internet at TV are controllable over Ethernet e.g. by 
the Samsung remote android app however mine does not connect to this.

Also the samygo firmware does not cover this model either so I expect 
there is some hardware missing for this capability... Odd really.

Annoying, if I'd known this control functionality was linked to 
Internet at TV inclusion I'd have got one.... Also given they run Linux its 
a little surprising one can not get any control over Ethernet.  Suppose 
could sell and upgrade but I am directed to save this cost....!!

It is however CEC capable, has USB and of course has IR...
