Re: lirc lirc-0.8.4a-1.fc10.i386 irsend not working properly for me

[Matt N. <ma...@fr...>]

Just to start simple and as a sanity check, did you set the transmitter?  I
did not see it in your description.  I have set mine like this:

# irsend SET_TRANSMITTERS 1 2
# irsend --count=1 SEND_ONCE YAMAHA_RECEIVER DVD_LD
