That's what happened when I upgraded my computer to Windows 7. In my case I have two real serial ports via a Vscom PCI200L, added by me. Before the upgrade the ports were COM1 and COM2. After the upgrade to Windows 7 they were COM3 and COM4. I was able to go to CONTROL PANEL|DEVICE MANAGER|MULTI_PORT SERIAL ADAPTERS. There I double clicked on "Vscom PCI200L controller", then clicked on the advanced tab and was able to rename the ports from 3 and 4 to 1 and 2. I've seen cases in the past where you were not able to rename the ports. I think it's a function of how the manufacturers implement their drivers.

The human has no control over what port number is used by the driver. Any program you are running which is looking for the K3 on a serial port may need to have the port number respecified after an OS change. 73, Guy ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
