[ubuntu] Screen session problem

view full story

http://ubuntuforums.org – Hello, I connect to my beagleboard by using screen from my Ubuntu PC: screen /dev/ttyUSB1 115200 and when I connect to my beagleboard I open the dev/ttyO1 by screen in the same terminal display. Now, I want to close only the last screen connection. But I cannot. When I close the screen session with ctrl+a d, it does not only close the last screen connection to ttyO1, it also closes the connection to the ttyUSB1,beagleboard. (There is only one window. Therefore I cannot use anything like ctrl+a w.) I want to be able to close the last screen session and go back to root@beagleboard r (Hardware)
