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?
Cheers,
Sam.
