Serial debug does not work anymore.
Serial Monitor opens with text ...
"Opening port
Port open "
but Serial.println(F("abc")); is not played back.
Micro Debug Trace window shows ...
"Launching Debugger...".
After disconnect from port, "Serial Monitor" shows "Port closed".
Micro Debug Trace window shows ...
"Debugging has exited".
"Expression on Com3" shows "Expressions Watch Window: Waiting for debugger breakpoint data. 

tips:- 

Add messages and/or {variables} and {function()} to..." but action like "{@Plot.MyPlotWindow04.ARead_1.Blue AR1}" are not processed.
Under Arduino IDE2 the Serial Monitor can display everything without problems. I have already searched for settings on your homepage and uninstalled and reinstalled Visualmicro. Unfortunately without success.

Switch the configuration name on the toolbar from Debug to Release, then upload again.

Please folllow the guide in yellow above.

Also show a screen shot of the serial monitor wide enough to see the settings.

Thanks for the screenshot and logs.

Can you set the Debugger to None (vMicro > Debugger > Debug > Debug: None.

Then re-compile and upload the project and check the Serial Output for the messages from your code?

Hello Simon,
I only see a difference in the "Debug Trace".
Look into the email from March 24.There is a screenshot there.

It seems to be a problem with the Stm32F401. With the ESP32 the Serial Monitor and the Serial Debug window opens. What settings can I set for the Stm32 ? I also use a ST-Link V2 clone for the Stm32F401.

Thanks for the update.

With the STM32F401, when your Serial Messages work in the Arduino IDE, are you just using the standard Serial.println() calls in your code? (or a different Serial Object)

Have you tried changing the DTR and RTS Settings in the Serial Monitor in Visual Micro when running a sketch without the Serial Debugger, and just your own print statements?

Enabling the DTR in the monitor is the most important for most boards. It causes a reboot so you can then see serial messages from the setup(). The Arduino IDE always has this setting on and does not allow it to be switched off.

Hello Simon,
It seems to have been located on the DTR. 
Thanks very much

Thanks for the info. The esp32 provides a special configuration property that notifies the IDE not to use DTR. That would force it off, we will look into why subsequently using a different board does not switch it back on again. Your manual setting overrides.

Question to help us test this. Did you use the stm32 with the same project as the esp32 or were you using two different projects?

For testing I just created a small program and ran it with ESP32 and Stm32.
void setup()
{
    Serial.begin(115200);

}

void loop()
{
    int Taste3 = 7;
    delay(200);
    Serial.print(F("Taste_3    = "));
    Serial.println(Taste3);

}
