All, I have DX4WIN 9.0.9 running on a Windows 10 PC which has one build in hardware serial port which is connected to my Kenwood TS-950SD via the Kenwood IF-232. I then have a USB 2.0 to Serial (FTDI chipset) adapter plugged in to a USB 2.0 port (COM9) and configured DX4WIN to use COM9 for CW keying. I built a home brew interface and it works fine but the problem that I have is that sometime when the computer starts up, after having been turned off, and I launch DX4WIN I get an error dialog that says "Could not open COM9 for keying: ie_Open - device already open". At first I started going in to File->Preferences selecting a differenc com port (non existent) for keying and saving changes (got an error that the Com port is not available - which was expected. I then repeating this and re-selecting COM9 and saving and no error message and DX4WIN keying works fine.
I then tried something different - when the error occurs I just do a File->Preferences->Save Changes and Exit - WITHOUT making any changes. This results in CW keying working fine. I then found that if I repeat this again, save changes without changing anything I will get the 'already open' error. Every other time I save changes I get the error. And this happens even when NO changes are made, just open preferences and immediately tell DX4WIN to save preferences. This is not a big deal but it is annoying and I am hoping someone out there has a solution.
