I have a Pro-93 scanner where the LCD screen suddenly stopped working (the backlight still works). I've determined from other post I need to try reinitializing the scanner. I previously purchased a radio shack cable and downloaded the win93 software. Problem is I can't get the program to download my frequencies from my scanner. On ports 1 and 2 I get the error "unable to open the port:\\.\COM1". if i select a port 2 or larger i get "expected to read back the data we just wrote - this failed. ensure the correct COM port is selected, a supported cable is attached to the COM port and the scanner, and the scanner is turned on" I am running this on windows vista.
