Debugger Stops when external app attached

G'day
I am trying to debug a Mega script while the Mega is being controlled by and external app. I have the set the project properties local/remote to debug via the Mega's serial1/COM12. I upload the script via COM11.
As soon as I connect my external app to COM 11 loop() freezes/crashes. No errors are output. Is there a log file anywhere I can see what is going on? All the doco states that the VMD should release COM11 after the script is uploaded.
Thanks in advance
Tim

Hi,

Great, thanks for the update.

Info if useful in the future...

It isn't visual micro that directly performs the upload, both visual micro and the arduino ide use a tool called avrdude.exe that is supplied with the arduino ide.

Yes avrdude shuts down the port after upload and we know that happened because your app connected using the port. Your app would fail to open the serial port if the port was still in use, therefore would not able to connect (or communicate the 2560).

If an app connects and it has enabled the DTR property on the windows COM port. then the 2560 will reboot.
