thanks for your reply and sorry for confusing.

My requirement is quite different and crazy.
In a very simple sense, say I have two ssh terminals opened on /dev/pts/0 
and /dev/pts/1 . Now I have to to push a command from pts/0 to pts/1 and 
execute on it and then control the program from pts/1 as usual.

Thanks
