I want to monitor and log a pseudo-terminal device /dev/pts/12 (for debugging purposes), i.e. I want to see what gets written to the terminal and I do not want any process using the terminal to notice.

The obvious solution 

     cat /dev/pts/1 
     cat </dev/pts/1

does not work: at best, it seems to capture only keystrokes.

In other words, I'd like to have something analogous to the output of script -t file.timings typescript ; but I also need the keystrokes. Reptyr -l $PID is another program that might help: it redirects the output of a process $PID to another /dev/pts or pipes.

For normal tty's you got screendump or even cat the vcs file but afaik there is no way to do that on a pseudo-terminal, at least the easy way, maybe you should look this:

Conspy

Hope this helps
