cat /dev/vcsa(VC number) > screenshot.vcsa
This grabs a copy of screen memory of char/attribute pairs in the same manner that the screen is organized under MS-DOS, etc..
If you dump this file back to a vcsa device, you'll be viewing it on that vc.
If you just want the text without the color stuff, use the /dev/vcs(VC number) devices instead.
