Thanks for the idea. Unfortunately I am out of slots. It is a MicroATX mobo
and it only has 2 PCI slots. I have the nic and PVR-250 in it so they are
I was hoping I could someone allow the slave access to the serial port on
the master, install LIRC on the slave, and then config it to use that
device. I thought it was a long shot, but I thought it was good to ask
before I spent more money.
Can one recommend an easy to setup USB IR Blaster? or have any more ideas?
