# Runs Proxmox serial console. If it fails it tries again... and again... and again until it succeeds. This is very
# useful when stopping and starting VMs with multiple serial ports. Without it every time you stop and start a VM you
# have to go and open all serial consoles again manually.
# To exit this script press Control+C twice (or if console is active Control+O and then Control+C twice).
