This is an FYI regarding software you might want to use when troubleshooting
CAT or other serial (or parallel) port issues. It is not a solution in itself
but it is a tool that will show you what information is being transported
across a computer link. This is a stand alone program called PORTMON.EXE and it
runs on Windows systems up to and including XP.
You can read all the details regarding this free utility and download a copy
here:
http://www.sysinternals.com/Utilities/Portmon.html
Your virus software may report this tool as a trojan or as high risk software.
Use portmon.exe only when you are troubleshooting a communication problem.
Here's one report to review regarding this possibility:
http://www.auditmypc.com/process/portmon.asp
Most recently I used this utility when working with the programmer on the AEA
HF Analyst product line. We were having a stubborn startup/initialization issue
that was resolved after using PORTMON to view the serial handshaking between my
PC and the analyzer.

Tom,
Your message is interesting as I am experiencing the same problem with my
FT-1000D and RIGblaster pro. Since Tech support of W.M.R. could not
solve it, I am wondering to try your solution. However, before that, I want
to ask my friends on this ML if there is anyone who is using FT-1000 and
R.B. pro and whether you have any problem or not.
As I am not technical and totally stuck, any advice would be most welcome.
