| Post subject: | IR Blaster on USB to Serial Adapter (no serial port) |
I decided to upgrade the motherboard and cpu on my Backend/Frontend Server today. All was going well until I tried to hook up my Serial IRBlaster via my Keytronic USB to Serial adapter. I have used this adapter in the past. In fact, I bought it a few years back for another Knoppmyth machine that did not have any serial ports. If memory serves me correctly, I ended up replacing /dev/ttyS0 with a link to /dev/ttyUSB0 and that worked. I quickly found that udev no longer allows that simple fix. Anybody have any ideas? What does everyone do these days? Does everyone just buy a PCI or PCI-x serail card? |

From some of the posts I've read on the net... You can NOT take a serial (rs-232) ir blaster and connect it through a USB-Serial converter. LIRC handles the bitrate modulation directly, and this will get lost through a USB converter. If you want to keep the serial blaster, get a PCI serial board. Otherwise look for a USB ir blaster to replace it. |

What I find really odd is that I used to use the USB to Serial adapter with a SFF system that did not have a serial port a few years back and it worked fine. But... maybe it wasn't the irblaster. Maybe it was a serial connection to the cable box. I have ordered a serial card and will try that. The days of serial ports on motherboards are numbered anyway, Are there any good usb ir blasters out there? |
