Raw send and recieve

[Rowan M. <ro...@hi...>]

Hi List,
    I have a serial rx/tx solution I bought from eBay and it's working
great with LIRC.  Very well actually, it's better than the receiver
built into the tv!

http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItemVersion&item=200205713612&view=all&tid=508107473010

So everything is all good, except now I want to control my aircon
unit....

With mode2 I can see all the pulses and spaces and they are consistent
and don't usually vary by very much,
however irrecord, even in raw (--force) mode only picks up two dots and
then stops, failing to find the gap it says.

I understand the air con remote sends state packets rather than
individual control buttons.

How can I capture the input from mode2 and replay that signal exactly.
I will then, instead of decoding the packets, capture the settings
individually and replay the right packet.

So I want to end up with..

25 degrees cooling fan full
26 degrees cooling fan full
27 degrees cooling fan full
25 degrees heating fan full
26 degrees heating fan half
27 degrees heating fan low

(degrees C for those who think im crazy :)
etc etc...


I tried to do:
# cat /dev/lirc0 > capture.code
... and then ...
# cat capture.code > /dev/lirc0  

but that fails with an IO error, even as root.

How can I capture the mode2 output and convert it into raw config codes
to use with irsend, or is there another way I can do it?

Cheers,
  Hippy
