How much output are you expecting to capture?  You can configure an
arbitrary number of syscons history lines or screen scrollback lines.  I'm
sure xterm can be configured similarly, but I can't find it from a quick
skim of the manpage.  I have syscons set to 1024 lines and screen set to
10240 lines myself.  You can use vidcontrol -HP to dump syscons history if
you need to copy more than you can select with the mouse on a single page,
and screen has a whole sub-interface for interacting with its scrollback.
