I'm using screen /dev/tty.usbmodemxxxx to debug a physical device. An unavoidable part of my workflow disconnects and reconnects the device, causing screen to terminate; so I need to start it it up again.

Is there a way for me to say "keep screen alive listening on /dev/tty.usbmodemxxxx - just hang while it's not connected"?

  • How do you start the screen ? What do you see in "screen -ls"

Just a hack but you could write a wrapper script like:

#!/bin/sh
while [ TRUE ]
do
screen /dev/tty.usbmodemxxxx
read -p "connect again?"
done

and CTRL-c it when you want to stop.
