Are you using a USB-to-Serial adapter? Did you install an updated device
driver? Are you also using a KXSER cable? Homebrew? Does the same
USB-to-Serial adapter and KXSER cable work on the XP computer?
Some USB-to-Serial adapters require power to work. Try setting DTR and/or
RTS to ALWAYS ON for the KX3 computer only.
I also suggest using USBDEVIEW to UNINSTALL any Prolific device drivers on
your Windows 7 computers. They have known problems and can interfere with
FTDI USB-to-Serial adapters, if both device drivers are installed on the
You also mentioned using a band decoder. What type? Is it using the same
What do you see in device manager?
