If you cannot use different remote codesets for both boxes, and need
to use 2 separate serial transmitters, you may need to build 2
independent installations of LIRC, as LIRC previously would not work
when 2 separate devices needed to use the same kernel module
(lirc_serial in this case).

I think it is now possible (haven't done this personally but have seen
write-ups) to run 2 instances of lircd (one per device) from the same
installation of LIRC, which simplifies things no end. I can't say 100%
that this works though, as I've always built a separate instance of
LIRC when faced with this situation. I'm sure there was a link to such
a write-up on the MythTV Wiki, but I can't see the link anymore:
