Re: Simultaneous transmit and receive?

[Steven B. <sab...@ea...>]

Thank you very much Jason for posting this -- it was *exactly* the starting
point I was looking for.  I'm now successfully receiving using my Hauppauge
remote, and transmitting using my Actisys 200L.

Some additional notes for anyone trying this:

- If you're using devfs (as Mandrake 9.1 does in my case...), you'll find it
complains in dmesg about /dev/lirc not being a directory as you modprobe the
two devices and load the two daemons.  The solution I used here was to rm
the /dev/lirc node and let devfs make it's own nodes instead.  It puts them
in /dev/lirc/0 and /dev/lirc/1 in the order loaded.  You then specify the
correct path in each lircd call with the -d parameter.  i.e.:

/usr/local/sbin/lircd -d /dev/lirc/0
/usr/local/lirc-xmit/sbin/lircd -d /dev/lirc/1 /etc/lirc-xmit.conf

- It's important to specify the proper lircd device when doing a send as
well.  Here's an example:

/usr/local/lirc-xmit/bin/irsend -d /usr/local/lirc-xmit/dev/lircd SEND_ONCE
gi-motorola-dct2000 3

...will transmit a 3 using the transmit device.  (I'm not sure it makes any
difference which irsend you use, BTW, but I'm specifying the path just in
case...)


Now if only my cable box would consistently pick up what I transmit...
<sigh>
