Have run into the same troubles and I had to smile when you mentioned trying to find out which port was which...been there. Julian I recently purchased over E-bay an Edgeport device. You can hook up to 8 serial cables into it and then there is a USB cable into the PC. Have not had a chance to use it yet but have read it works great. This may be another option if you run out of card space in the PC.VE9KK https://www.blogger.com/profile/04720839744779758420noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-37498795124783804702010-09-24T18:55:12.193+01:002010-09-24T18:55:12.193+01:00Windows has a long memory of a port ever being use...Windows has a long memory of a port ever being used. Virtual ports are particularly bad from that standpoint. However, as you have found, ignore the whining and with a reboot all will be well. Assigning two logical ports to one physical port is still a bad idea though. ;) I have a null modem termination, which basically straps TXD to RXD. I plug it into a port, then work through the logical port numbers with a terminal program until it echoes. If so, I label it and move on.Tregonseehttps://www.blogger.com/profile/01705100658499499100noreply@blogger.com
