There's only lirc device, and since the receiver part works fine, that
can't be the problem... unless the transmitter part needs a separate
device node?

Anyway, I've come to a solution, though it's a bit on the ugly side.
I ended up building a serial port blaster, and it worked... kinda.
The STB would see most of the button press events I'd send, but for a
3-digit channel change, that meant success was well under 50%.

I ended up disconnecting the IR emitter from the serial port blaster,
and connecting the wires where it used to be directly to the leads of
the IR detector in the STB.  Now it's worked 100% of the times I've
tried.  I was just wondering, if anyone happens to know, if it would
be a good idea to put a resistor or diode somewhere in the line to
prevent an overvoltage problem?
