请问NMUDP这个控件应该怎么用

[robinhunter]

procedure TForm1.Button3Click(Sender: TObject);
var
buf:array[0..9] of char;
begin
buf:='dafdsfa';
nmudp1.SendBuffer(buf,10);
end;

procedure TForm1.NMUDP1DataReceived(Sender: TComponent;
NumberBytes: Integer; FromIP: String; Port: Integer);
var
buf:array[0..9] of char;
begin
nmudp1.ReadBuffer(buf,numberbytes);
showmessage(buf);
end;

把remotehost设成127.0.0.1就可以自已跟自已通讯了，进一步还是自已看帮助吧
