Delphi cctalk protocol to implement a coin acceptor

I want to integrate a coin acceptor into my Delphi 7 Application. This specific coin acceptor uses the ccTalk protocol.

I've been looking for a ccTalk library which I can use from delphi.

Any of you guys know of any ccTalk libraries out there? Thanks

I think I must use a comport component, here some code

procedure TForm1.Button_OpenClick(Sender: TObject);
begin
  try
    if ComPort.Connected then
      ComPort.Close
    else
      ComPort.Open;
  except
    ShowMessage('Connection error !');
    exit;
  end;

end;

procedure TForm1.Button_SettingsClick(Sender: TObject);
begin
  ComPort.ShowSetupDialog;
end;

procedure TForm1.Button_SendClick(Sender: TObject);
var
  Str: String;
begin
  Str := Edit_Data.Text;
  if NewLine_CB.Checked then
    Str := Str + #13#10;

  try
    ComPort.WriteStr(Str);
  except
    ShowMessage('Comunication error !');
    exit;
  end;

end;

procedure TForm1.ComPortRxChar(Sender: TObject; Count: Integer);
var
  Str: String;
begin
  ComPort.ReadStr(Str, Count);
  Memo.Text := Memo.Text + Str;
end;

If I call Button_SendClick with 开发者_开发知识库string "000 000 001 245 010" nothing happens ....

Here's the device protocol manual.
