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 anything. 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? Thanks! mjt |
