Identifying the Enter pressed by the user in the Inputfield

Question

Hi all,
We have one Comment field on Portal screen that is given by the user (User may press enter while giving the comments). We are sending that field value to R3 through RFC and when we are getting back that comment field value from R3 we need to identify the Enter pressed by the user. We are writing the code for identifying "/n" in that comments field but that is not working. Can anyone help me out in this? This is really urgent.
Thanxs in advance!!!

Hi Gurmat and Manoj,
                               Do you want to replace the TextEdit too? I thought only to print or send to backend. No problems. We can do change in TextEdit as well.
My input in TextEdit is:
How
are
you
Manoj?
After button click I got output in TextEdit and TextView(I used button to trigger event):
How are you Manoj?
In onActionButton() my code is:
StringBuffer buffer = new StringBuffer(wdContext.currentContextElement().getText());
     for (int i = 0,index=buffer.indexOf("\n"); i < buffer.length(); i++) {
     if(i==index){
          buffer.replace(i-1, i+1," ");
          index = buffer.indexOf("\n");
          if (index==-1)
          break;
In StringBuffer use "" only
regards,
Siva
