The user must first enable serial port access to a given VM by setting the 'serial-port-enable=true' metadata key-value pair. Setting 'serial-port-enable' on the project-level metadata enables serial port access to all VMs in the project. This command uses the same SSH key pair as the `gcloud compute ssh` command and also ensures that the user's public SSH key is present in the project's metadata. If the user does not have a public SSH key, one is generated using ssh-keygen. ## EXAMPLES To connect to the serial port of the instance 'my-instance' in zone 'us-central1-f', run: $ {command} my-instance --zone=us-central1-f Tc [RRU5 URSSSS9 URS[R SSS9 URS S S S 9 URS [ R"S S90SSR[5S9 URSSS9 [R"USSS9 [R"U5 g)zPSet up arguments for this command.
