LinuxQuestions.org - Connect from one pts/* tty to another?

Say I have left an SSH session open at work. Now I go home and connect another SSH session with the same user.

So now when I list the users I get: -

Code:

 22:34:22 up 28 days,  6:03,  2 users,  load average: 1.54, 1.48, 1.26

USER    TTY      FROM              LOGIN@  IDLE  JCPU  PCPU WHAT

root    pts/0    10.2.3.4    09:32    5:47m  0.50s  0.50s -bash

root    pts/1    10.6.7.8      22:26    0.00s  0.15s  0.00s w

Is it possible to connect from pts/1 to pts/0 into an interactive shell? I know people have suggested things like screen or VNC but surely there must be a *nix cli tool to connect from one to another, right?
