I had the same problem using a Dell XP Pro desktop computer and a Belkin USB/Serial 
adapter which worked fine with everything else, including the K3. I then tried a Win2K 
laptop with a real serial port and it worked. Finally, I hooked the Belkin adapter to the 
  laptop and it worked there too!

I checked the port speed, etc. I'm afraid I don't know what to suggest except 'try a 
different computer'.
