[Dx4win] IC746 Rig Control

[Scott Neader KA9FOX]

First, I got the RTTY working in DX4WIN with my new Microham  DigiKeyer... 
I had to tell MMTTY to use a different device (the default device is 
"-1").  Works great!!

I'm on a different mission now... trying to get Rig Control working between 
my IC746 and DX4WIN, using the built-in CI-V interface in the Microham 
DigiKeyer.

DigiKeyer USB Router Settings:
   Control:  COM8

IC-746 Radio Settings:
    CI-V Baud Rate: 4800 (although I've tried AUTO and 19200)
    CI-V Address: 56h
    CI-V Transceive ON (but have tried OFF)
    CI-V 731 Mode OFF (although I have tried ON)

DX4WIN Software:
     Second Radio:
          Type:  ICOM 746
          Address:  56
          Baudrate:  4800 (although I have tried 19200)
          COM Port:  COM8
          Poll Rate (ms):  5000    (have also tried 1000, same as my MP)
          Max Tries:  6                (default value)
          DTR High:  YES   (although have tried to turn off)
          RTS High:   NO


In the USB Router, while DX4WIN tries to see the radio, it shows "Open" 
4800 8N1 with the red and green arrows blinking.  But then eventually 
DX4WIN says "radio timeout, radio disabled" and then the USB Router shows 
"closed"

Thanks for any pointers!
