Serial Port will not open in Windows 7 Pro
Posted on 2011-02-22
I have a device that will take 4 serial ports and and allow you to connect to them via ethernet. You assign the device an ip, load the device driver and the ports show up in windows just like real com ports. This worked great on my XP Pro notebook. I now have a Win 7 Pro machine. However I cannot seem to get the ports open.
I have loaded the device driver and windows shows the ports and say they are working correctly. When I try to open a port with Hyperterminal windows tells Unable to open com 4 please check your port settings. I get the same result for com 1, 2, 3, 4 which are the ports that show in the device manager. If I remove the device the results is the same. If I choose a port that doesn't exist I get the same message.
I have tryed to run Hyperterminal under XP pro and run it as admin, still the same result.
Thanks in Advance for your thoughts.
