[mythtv-users] IR Receiver/Transmitter Setup

[Mike Smith]

Hi,

  This was addressed a couple of weeks ago.  Seems
to work.  I cut and paste the response below.

Thanks so much. I think my main problem before this
was not knowing 
this
modules.conf trick,  I was sharing the same
lirc_dev.o:
> alias char-major-61 lirc_sir
> below lirc_sir lirc_dev
> alias char-major-62 lirc_serial1
> below lirc_serial1 lirc_dev1

I did not know the below line mentioned by Sriram.

Thanks again.  I actually have it working now.  Mike
