Does anyone know how to open serial port so I can see Linux on bootup?

How can I open a Sketch / Serial Monitor to watch the Linux on bootup (console)

in other words how do I get to the screen below:

(the only reason I see it now is becuase I enlarged my SSD on Linux so it shows Linux after it’s done, but if I close it, how do I bring it back?)

Regards,

Sean.

Load the bridge->yunserialterminal example and press the yun reset button by the LEDs.

There is a FAQ subject on yun startup explained that may be useful.

THANK YOU SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
