Hello all,

I am trying to set up a simple serial receiver that would work with my 
TV remote control . But I am stuck at one point and , although searched 
a lot through the web, followed all basic and advanced recommendations, 
I must admit I can not make it work for the moment Sad

I have soldered the simple serial receiver from lirc.org on my VIA EPIA 
800, taken care about the recommendations on the low supply voltage 
provided on those motherboards. So I am almost sure the hardware is 
working.
    

  Have you checked the circuit with a multimeter or scope?  Check
the regulator output is 5v, the output of the receiver should toggle
when it sees a signal.

Yes I have checked the circuit with  multimeter.
The regulator output is 6.15 V, it is external, since I dont have enough voltage on the RTS pin from my VIA EPIA board (only 4V).

When I check the receiver output, I have a 4.04V toggling when I press remote button downto 3.04 V.

For me, this means that the circuit is ok.

I then followed a wiki lirc howto 
(http://knoppmythwiki.homelinux.org/index.php?page=LIRCHowTo)
I have found my Sony remote control in the - excellent - remote config 
site from lirc.org (http://lirc.sourceforge.net/remotes/), loaded my 
lircd.conf at the right place.
but ... no way ! when I come to mode2 attempt : nothing reacts , as if I 
had nothing on the serial port Evil or Very Mad

Here are my logs :

*Code:*
root@mythtv:/home/mythtv# dmesg | grep lirc
lirc_dev: IR Remote Control driver registered, at major 61
lirc_serial: auto-detected active high receiver
lirc_dev: lirc_register_plugin:sample_rate: 0

    

Most receivers are active low type: the output is normally high
and is pulled low when it sees IR signal.  I have not come across
a active high receiver, most are active low.  So this could
indicate your circuit is broken.
I agree with you that it should be recognized  as an active low receiver.
But still dont know what to do to repair it ...

Other ideas ?
