[Dx4win] CW Keying Com Port issue

[Rick Stoneking]

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.

 

Thanks

Rick
