public class ConexaoTELNET {
    private TelnetClient telnet = null;
    private InputStream in;
    private PrintStream out;     
    private ConexaoBean conexao = null;
    
    
    public ConexaoTELNET() {
        telnet = new TelnetClient();               
    }

    public void getConexao( Object bean){
        
        conexao = (ConexaoBean)bean;
        
        try {
            
            //Conexão com o servidor
            telnet.connect( conexao.getHost(), conexao.getPorta() );
            //Entrada e saida de parametros
            in = telnet.getInputStream();
            out = new PrintStream(telnet.getOutputStream());            
        }
        catch( Exception e ) {
            e.printStackTrace();            
        }        
    }
    
    public String getComando(String comando){
        String retorno = null;
        
        try{        
        int ii = 0;
		
		byte[] tmp = new byte[1024];
        
        out.println(comando);
        out.flush();
        
        while (in.available() > 0) {
			int i = in.read(tmp, 0, 1024);
			if (i < 0)
				break;
			ii = i;
			retorno += new String(tmp, 0, i);
        }
        }catch(IOException e){
            e.printStackTrace();
        }
        
        return retorno;
