I am trying to figure out how to change to Virtual Consoles 2-4 on a target system using PuTTY and screen. I have read the screen man pages and the replies here, but I still can't figure it out. These are systems booting off of a network image that I don't have control over, so I can't just install tmux, which seems to be the "best" option.

Is there a simple screen command I can use to switch to / see / control the virtual consoles on my systems? I need real examples, as the ones I've seen in the man page and other searches have not been helpful. I need to see the actual Virtual Consoles that already exist on the target, not just create new ones via "Ctrl+A, C" in PuTTY, as these systems have processes running on different consoles I need to be able to see and control.

The answer in the linked page notes that you cannot connect to different virtual consoles using ssh, and recommends using screen or tmux (which are different).

If you had a screen or tmux session running on the remote machine, you could attach to that and see what is running in each of the session's "windows".

Without that, the most you could do would be to read the standard-output device for the process that you want to inspect. But as noted in Why can't I tail -f /proc/$pid/fd/1?, it is not really that simple.
