Hi Manu,

LIRC is a tool for recording IR signals, recognizing, and storing in a 
compact format, and retransmitting them. It was never intended as a tool 
for analyzing and generating arbitrary IR signals. It records the signal 
it its own, essentially undocumented (although open source) format. If 
you are looking for tools for analyzing/generating/converting general IR 
signals, let me suggest that you have a look at IrScrutinizer instead. 
(http://www.harctoolbox.org/IrScrutinizer.html) -- also free software.

(I suspect a lot of people on this list  disagree -- so speak out! Yes, 
I know how to send raw signals etc, and how to "look at" mode2.)

The WinLirc project tried to document the semantics of the configuration 
files -- and got it at least partially wrong. Also, there are some 
comment in the code, please look at the very latest git-code  and 
process it with doxygen. In particular lirc.h and ir_remote_types.h are 
interesting. For the rest, "use the source, Luke".

Greets,
