It uses a common IR receiver module which demodulates the 37.9kHz and
outputs the logical signal bits directly. Actually it's the 940nm IR
light
wave which is modulated at 37.9kHz and pulsed with the logical signal
for
the coding and protocol which is RC5 here (manchester coding.)
Does it mean that the fux does recieve the digital raw output exactly
like as if the IR transceiver was on board, which would mean the
possibility of having a /dev/lirc and a tty?
No, Tux gets it but needs to send that through the RF frames so the
received signal has to be coded somehow. But then on the other side (fux)
we could expand the code into something lirc can accept, or that can be
done n the computer by the daemon or anything else.
