The 'Amnesiac' screen s set up when FreeBSD starts up

[gs_stoller at juno.com]

	When  FreeBSD  starts up, you see a screen (on an  IBM PC )
with a heading line that says:
		FreeBSD/i386 (Amnesiac) (ttyv0)
It is followed by a blank line and a "login:" line.  There are 7 other
like screens with heading lines that differ in the digit following
"ttyv", in those it ranges from  1  to  7 .  One moves from one of these screens to the one that announced itself as  ttyvj  by depressing
an  Alt  key and the function key labelled  j+1  simultaneously.
If one is in  Xwindows , one switches to screen  ttyvj  by depressing
 Ctrl  &  Alt  keys and the function key labelled  j+1  simultaneously.  One can return to the  Xwindows  screen by depressing an  Alt  key and 
the function key labelled  9  simultaneously.

	Is there a command that tells one on which screen one now
sits, and if so what is its path-name?  Where are these screens
set up, and can one change that, say adding new screens?
