So it depends on your terminal as to whether hitting 'F2' 'just works' For
Gnome terminal and Konsole and xterm at least, it just works (F1 is sometimes
hijacked for 'help' by the terminal, but that can be configured.
Failing that, hit <ESC> 2 for F2, <ESC> 3 for F3, and so on (<ESC> ! For F11,
<ESC> @ for F12). That's hitting escape, releasing escape, hitting number (or
shift-number).
BTW, that was for sending the function keys, which actually wouldn't be the
answer to your real problem. It'll help get you into setup (though I just do
rsetboot <node> setup so I don't have to hit a key) and such, but your
situation is actually different.
Your question is about virtual consoles (tty1, tty2, etc.). Linux does not
have VCs over serial. RHEL/CENTOS7 installer works around this by running
everything inside tmux (and xCAT-genesis similarly runs everything under screen
to allow switching to a new shell at any time). But for RHEL6 and SLES and
Debian/Ubuntu, no such luck. I recommend always running screen or tmux so you
effectively get that capability when you have a choice. As a bonus you get the
ability if you are in that habit for ssh sessions as well (and can resume where
you left off if you lose networking)
Limitation also holds for ESXi. Interestingly enough, Windows serial console
actually does support console switching on serial inherently, much to my
surprise.

Subject: [xcat-user] Function keys under rcons and wcons
Is there a way to send a function key combo to the system while using rcons?
For example, when Anaconda is running during initial provisioning of a stateful
system, it's sometimes useful to go to another TTY via F2 or alt-F2.
This works when viewing the console with iDRAC or iLO or VNC when the nodes are
virtual, but I haven't been able to send the key when viewing the node with
rcons.
Has anyone done this with rcons? Is it possible?
It looks like you can send an octal control value via ^Ec\ and then the code,
but it didn't seem to work on the system I was using.
Thanks,
Russ
