I have a GE Fanuc 90-30 that I used proficy to communicate to it serially via port 2 on the cpu 351.when connection in Proficy, it connects, but as soon I disconnect, no way to reconnect without rebooting the computer.the serial port is usb virtual and works fine. I do use the icon in Proficy to disconnect, and it shoes disconnected, but if I try to reconnect, it will tell me it is used by another program. Any way, Proficy does not release the port. The LM90 serial test is running in the background and tried to stop it in win 7 task manager, but not listed.

In win 7, device manger, refresh the port,but still needs to reboot. It takes a long time to debug this way.I also tried reconnectiong the cable, no change. Any idea of how to release the serial port? I have a GE Fanuc 90-30 that I used proficy to communicate to it serially via port 2 on the cpu 351.

You need to find out when LM90 serial test is started and Prevent it or turn it off. It should not be running, it is likely using the port. You may want to try a 'clean' re-install of PME if all else fails. Instructions for this can be found here: http://forums.ge-ip.com/showthread.php?t=16321.
