I've done all my JP1.2 work on my laptop. I had purchased a serial cable from Rob and used it with a Dynatex USB adaptor, and I've never had any trouble reading JP1.1, JP1.2 or JP1.3 using that cable. I'm not sure if it was a JP1.x or a JP1.2 cable, because I didn't pay any attention. Over the weekend I started setting up my new JP1.2 lab on a different computer. Since this computer had a serial port, I took off the adaptor and plugged it directly in to the COM1 serial port and I kept getting the "Failed to open JP1.x interface" message no matter what I tried to do. So I came into the office and downloaded the USB driver, connected it to my adaptor, and voile, my cable is once again reading JP1.1, JP1.2 and JP1.3 remotes. |

Vicky, did you check to see if the com port was active in both the bios and device manager? Also, it may be a different port number like com4. _________________ Nils

I have used other equipment connected to this serial port, and it always works as COM1. I plugged in some other serial device I had just to make sure the port wasn't damaged during transport, and that equipment responded as expected. I have not checked anything in the Bios, (is that the blue screen you get to before the windows starts?) But I'm assuming since other equip
Since I bought the USB adaptor specifically for this cable, this isn't really a problem for me. I just thought I'd mention it here. Actually since I have JP1.1, JP1.2 and JP1.3 remotes, this works out great. |

Oh well, it sounds like your port is working and for some reason IR is not seeing it. I assume you tried both the serial and the usb-serial options. _________________ Nils
