[Dx4win] TS-2000 Radio Interface Problem / Rig Contro

[Wayne Splawn]

Hi,
I recently downloaded a copy of DX4WIN, ver 8.04, and installed the license.
This effectively upgraded me from an earlier version that I owned.

I am seeking help because I have a problem with the radio interface software
not working for my TS-2000.  After starting the radio, the DX4WIN banner
will show "(not responding)" and an error message appears shortly after that
-  that message is "Radio timed out.  Radio interface has been disabled"

Radio Setup Parameters are:
.	Type=Kenwood 2000
.	Address=00
.	Baud Rate = 9600
.	COM Port = COM2
.	Poll rate = 5000; but have tried other settings
.	Max tries = 6
.	Transverter=0
.	Band= None
Menu 56 on the TS-2000 is set to 9600 baud.  Windows device manager reports
9600, 8, n , 1 for COM2 settings.

I am running the software on Windows-7 Professional and I have verified the
I/O address is 02F8 for COM2.  
I have tried Windows-7 native as well as the XP (SP3) compatibility mode on
dx4win.exe.  
I have tried DTR/RTS high and low.
I have tried other baud rates & settings but no change DX4WIN seems to work
fine for logging, etc.  Just the radio interface is the problem.

HERE'S THE CATCH:  The radio DOES respond to Kenwood's ARCP software without
any changes in cables, COM settings or other adjustments.  I can shutdown
DX4WIN and can immediately start ARCP--- ARCP works fine and I have complete
software control over the radio.  This leads me to believe there is
something in DX4WIN that I'm not setting correctly.

Can you offer any suggestions?

Tnx & 73
