Bash shells communication

Hello all,
I have the following problem. In a Bash shell I run a program (I don't have the source code) which will execute some steps. At every step the program will wait for a user input. So I would like that another script which is running on a different shell will send these input togheter with the "enter button pression". In a such way the software which is running on the first shell will advance according to the script.

Some ideas?
Thanks in advance.

If you have the input in file you can try something like:

program < inputfile
