2 Steps are required to make Creator not redirect the console output to its internal console:

a) Go to the Build & Run Settings of your project, select Run, in the Run Section, select "Run in terminal"

b) Go to the Application Output Pane. There is a wheel indicating the settings for the Aplication Output. Press it and select the "Terminal" section. There disable "Use internal terminal".

That's all. Pretty unintuitive:-)
