Hi screen users,We currently use Zterm to communicate with serial devices, but due to some problems it has I am looking for alternatives. screen was a good choice, but I have come across a stumbling block that I can't find a way around.
Basically, user A logs in (on Mac OS X machine), runs a script that attaches a screen to the serial device, gets their output from the device, closes the terminal window (without ctrl-A k) and logs out. When user B comes along, user A's screen still exists and hogs the connection to the serial device. Is there any way to kill user A's screen so that user B can make the connection (without forcing users to kill the screen with ctrl-A k, because I know they will never remember)? sending screen -X quit before opening a new screen doesn't work as user B doesn't have permission. Would like not to have to use multiuser and setuid root.
Any suggestions? Is there a way to tell screens not to be persistent? Or is this something screen just isn't capable of?
