What data on /dev/ttyS2

Post by erdem_ua » Mon Nov 07, 2011 6:18 pm

I don't know actually but I got some data on /dev/ttyS2 port on D6000 TVs.
I just write down "cat /dev/ttyS2" and I got some characters. Don't actually know what this characters for.
Any one could guess? My guess is, it might be related with "eco sensor".

Some repeating data. 18 byte pattern easy to capture. But don't know what it means.
