Hi there! I'm trying to get lirc set up on one of my systems; but, as you
may already suspect, I'm having some problems.
As background, I'm using a homebrew receiver that I am confident works --
it works just fine with a vanilla lirc and vanilla kernel on my main
system, but my media system is being more reluctant.
Ok, so my story starts as such: it resisted any recognition on my
motherboard's serial ports. I tried everything -- it never detected a low
receiver, always a high one. As such, irrecord and so on never located
I checked my power supply outputs, and as it turns out my 5V output (which
I think I read somewhere was supposed to be the one that supplied the
serial ports with power) was reading somewhere around 4.7 or so. So I
replaced the power supply (with a cheaper one.) Still no luck.
(At this point, I should let you know -- I really did try a lot of things,
but I couldn't find any problems in the way I set it up or anything.)
Thinking my serial ports might be bad (even thought serial.o found them
ok) I bought a PCI serial port expansion card. It gets recognized ok by
parport_serial, and I can even probe the serial ports (using the io's
supplied by a modprobe'd parport_serial.) Thing is, I don't know the
right IRQ to use -- the one supplied by parport_serial is also used by the
PCI card, and when I try to run irrecord or anything, it tells me the port
is busy. (I assume this is from the PCI card using the IRQ as well, but
hey, I could be wrong.)
Has anybody gotten a serial-port expansion card to work with LIRC? Is
there a way?
