Yes, that isn't what I'm interested in.  There's screen (1) as well, 
which in combination with script (1) lets you have multiple windows 
open.  One can also direct logs and such to tty7 and read them with 
Alt+F7 from the console.  I was specifically interested in a scrollback 
buffer that is apparently supposed to be part of the kernel and wouldn't 
require redirecting to a file like you suggest with script (1).  One 
doesn't always know how much output will be generated when running a 
command and often one finds out too late that speech stops and text will 
not be spoken which has scrolled off the screen.  A good example is when 
I cat a README file.  I don't need to make a typescript because it's 
already a file on disk.  I don't really want to reread the file with 
more (1) when only a small amount of text wasn't spoken.  A scrollback 
buffer would be ideal.  Besides, I don't want typescripts taking up 
large amounts of disk space and I don't want to keep a record of every 
command with output for security and privacy reasons.  The .bash_history 
is bad enough.  Thanks anyway for the suggestion though.  That is a good 
idea when upgrading so you can see if anything went wrong and what.
