[Dx4win] Com port needing reset?

[Paul Ferguson]

I am using DX4WIN version 6.04 with Windows XP and an ICOM 756 Pro 
II. 

The Pro II is connected to the computer thru a homemade CI-V 
interface on COM3.

I recently added my SteppIR control box to CI-V bus and 
turned on the "Transceive" option in the Pro II. This configuration 
works, but a few times the radio interface has stopped working thru 
DX4WIN. "Start Radio" will not get it going again. The Pro II is 
still sending out data because the SteppIR continues to track the 
radio.

When the problem occurs, I have terminated DX4WIN and brought up the 
free program "Commander" to see if a different program can use the 
Com port to work with the CI-V interface. Commander does not 
communicate with the Pro II after the problem occurs. If I reboot XP, 
things are working again.

Anyone have a suggestion as to what is causing this problem?
