Hey I'm using Ubuntu 16.04 and I can't get the remote to work either.
I have tried doing 'cat' on /dev/ttyS0 and /dev/ttyS2 and /dev/ttyGS* but nothing comes out. I know the remote is doing something because I put a battery in it, and my infrared camera can see the remote flashing if I press a button.
I know this thread is more than a year old but I'm gravedigging it since there is nothing in the manual or forums about the remote control, it doesn't show up in lshw (It's not USB? I have lirc installed) and they aren't the most common devices on PCs so info online is scarce.
