I was actually thinking console for that part of the terminology, but
yeah, that's what I want to attach to, the man page didn't tell me how
though.

This seemed relevant:
     Output to a virtual console that not currently is on the display is saved
     in a buffer that holds a "screenfull" (normally 25) lines.  Any output
     written to /dev/console (the original console device) is echoed to
     /dev/ttyv0.

However, cat'ing and less'ing the device did nothing, except act as if
it were waiting for input, and none was coming.

I however did find out which screen I'm on using ps -A and grep:
sjss at legolas 12:01:15 (0) /ports/java/diablo-jdk15  > ps -A | grep tty
sjss              0.0   0   0:00.33  0.6  0      0    0 26343 26339
sshd: sjss at ttyp1 (sshd)
sjss              0.0   0   0:09.61  0.5  0      0    0 43906 43903
sshd: sjss at ttyp0 (sshd)

So, I want to see what is going on with ttyp0
ttyp0
