I have the same problem when running Fedora 11. I have to use it to run some older tests of our hardware. The kernel version is

Linux localhost.localdomain 2.6.29.4-167.fc11.i586 #1 SMP Wed May 27 17:14:37 EDT 2009 i686 i686 i386 GNU/Linux

No problem under Fedora 14. Screen version is the same in both cases: 4.00.03 (FAU) 23-Oct-06.

When I try to start a new screen it does not produce any output. The cursor freezes on the line below the screen command. The only way I've found to get out of the freeze is to press ^Z (suspend). When I type 'fg' screen complains that it can not find the session /var/run/uscreen/S-user/bla.bla .

This only happens on /dev/ttyS0. The S-user/bla.bla directory is not created.

It works just fine on /dev/pty/<number> and /dev/tty<number> terminals (pseudo and virtual consoles).

I can resume an existing screen session on /dev/ttyS0 using screen -r.

I can use this terminal to start a screen session by first executing an ssh localhost, which gives me a /dev/pts/<number> terminal, and then just type screen.

I run SuSE Linux 11.2 on a HP PC. I have a Wyse 520 terminal connected to the serial port /dev/ttyS0.

I run agetty on /dev/ttyS0 so that I'm able to log in on this terminal.

Starting screen on the virtual consoles works just fine. I think it's just the name ttyS0 that makes it impossible for screen to create the new session.
