Thank you, I found this one, now just to figure
out how to find process name.

 -- Function: process-send-string process string
     This function sends PROCESS the contents of STRING as standard
     input.  It returns ‘nil’.  For example, to make a Shell buffer list
     files:

          (process-send-string "shell<1>" "ls\n")
               ⇒ nil
