Is it a Belkin or Keyspan adapter?
Any brand but those aren't officially supported. I know
Radio Shack adapters don't work...and I get a message
similar to that when using them.
My Radio Shack Adapter works fine with the MX700 editor software running on WinXP Pro.
Any USB to serial adapter with driver software will create a COMx: port which should be usable by the MX700 software. If for some reason the USB to serial driver software creates a com port > COM9: (e.g. COM10:), the MX700 software will not be able to use the com port. In this case you go into the WinXP control panel and force the com port device name to COM1:->COM9:. Of course before you change the com port device name you should verify that there is no other active device which is using the com port name. Often there will be "phantom" COM ports left over from hotplugging other devices, which are not currently in use.
