I also used sofar the GNU Screen to connect to remote host through
serial connection:
screen /dev/ttyUSB0 115200

Sofar it works, but today I get the message:
[screen is terminating]

htop shows these lines for screen:
19038 csp        20   0 17244  2496  2300 S  0.0  0.0  0:00.00 screen
/dev/ttyUSB0 115200
19039 root       20   0 17244  2348  2044 S  0.0  0.0  0:00.00 SCREEN
/dev/ttyUSB0 115200

So I must first kill these two processes of screen, and after that I can run
screen /dev/ttyUSB0 115200
command, however, the GNU Screen is empty, so it is useless.

Before, I just hit Enter to get the login prompt in Screen, but now I
get nothing.

Ti trace the cause of problem I follow advices here:

sudo strace -ff -p 1696 -o straceGNUScreen

gives three output files:

What can cause my problem?
