Recently, while writing Excel VBA code for tools to manage the Kenwood 
TS-590S, I found the need to monitor the CAT commands issued by my 
software to the radio, and to check the responses from the radio.

I have now documented the procedures, in "How To Monitor Kenwood TS-590S 
CAT Commands". Following these procedures, you can monitor the CAT 
traffic between well-known applications (such as HRD, Fldigi, etc) and 
the radio, and also generate your own CAT commands using PuTTY.

Two other very useful utilities are briefly described: USBDeview and 

Although written primarily with the TS-590S in mind, the procedures are 
in fact usable with almost any radio that supports CAT commands.

To download the HOWTO, go to the TS-590S Resources Page:

Scroll down to the "HOWTOs" section, then click on the link:

"HOWTO monitor TS-590S CAT commands".

This is the first version of the HOWTO. If you have any feedback, or 
find any errors or misleading statements, please let me know.
