Bug Description

I use screen to connect to serial ports: "screen /dev/ttyS0". If there is
minicom running, it does not allow to run second minicom by using
/var/lock/LCK..ttyS0 lock file. screen does not look on this lock file and it is
possible to run minicom and after that to run screen with the same serial port.

Still the case in precise.

It though emits a short warning message if there's already a minicom using the same port:

SetTTY (fd 6): ioctl failed: Interrupted system call
