[RTTY] FT990 CAT problem

[Robert Chudek - K0RC]

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:

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:

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.

73s, Shin JR1NHD
