problème pour faire une action toute les secondes

Bonjour,
J'ai un un prog qui permet d'envoier et recevoir des informations via le port com.
J'ai 15 requettes à envoier sur un modem je l' fait grace a ce bout de code :

public String read(String string)
    {
        String chaine = "";
        byte[] readBuffer = new byte[20];
        try
        {
            outputStream.write(string.getBytes());
            outputStream.write("\n".getBytes());
            int numBytes = inputStream.read(readBuffer);
            for(int i=0; i<numBytes; i++)
            {
                chaine = chaine + (char) readBuffer[i];
            }
            chaine = String.format(chaine);
        }
        catch (IOException e) {}
        return chaine;

    }

Le souci est que je recoi tout a la fin mes 15 requette tout s'affiche en meme temps j'aimerais recevoir seulement 1 à la fois.

Mon code de requette est :
private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {                                        
    jTextArea1.setText("");
    String resultat0 = manager.read("+++");
    jTextArea1.append(resultat0+"\n");
   
    //Lecture S201
    String resultat1 = manager.read("ATS201?");
    jTextArea1.append(resultat1+"\n");
    resultat1 = resultat1.substring(5,resultat1.length()-1);
    jS201.setSelectedIndex(new Integer(resultat1).intValue());
    if (resultat1.equals("0")||resultat1.equals("1"))
