I need to save the whole output of Screen to a file to check later all the content.

The reason is that I'm dumping a flash memory through a serial port, using Screen to interface with it. I would like to save it to a file to check memory structure.

I've tried:

$: screen /dev/ttyUSB0 115200 >> foo.txt
$: screen /dev/ttyUSB0 115200 | tee foo.txt

And I've also tried to use bufferfile from screen, but I don't understand how to use it.

Is there an easy way?

There is a command line option for logging. The output is saved to screenlog.n file, where n is a number of the screen. From man pages of screen:

‘-L’ Tell screen to turn on automatic output logging for the windows.
