</div>Could you please detail how did you make the serial ir blaster? I am<br>
looking to make one myself despite having a usb-to-serial adapter<br>
instead of real serial ports. thanks.!</blockquote><div><br></div><div>A Serial IR blaster won't work with a USB-to-serial adapter, sorry.</div><div><br></div><div>The reason being is that lirc is not using the serial port as a 'real' serial port, it's manually toggling one of the status pins high/low at 40,000 times a second (or 56,000/sec in some cases) to generate the IR carrier... Something a USB-Serial adapter can't do.</div>
<div><br></div><div>If your motherboard has a 'real' hardware serial interface, or you add a pci serial card, you can build a serial blaster. Check <a href="http://lirc.org">http://lirc.org</a> - the "Supported Hardware" "Home Brew" "Serial Port Transmitter". </div>
<div><br></div><div>If you insist on USB, you'll have to shop around for a lirc-compatible usb blaster. (note: not a USB->Serial adapter, a purpose-made USB attached IR blaster.)</div><div><br></div><div>J-e-f-f-A</div>
