{ Important: Methods and properties of objects in VCL or CLX can only be used
  in a method called using Synchronize, for example,

      Synchronize(UpdateCaption);

  and UpdateCaption could look like,

    procedure TComBufThread.UpdateCaption;
    begin
      Form1.Caption := 'Updated in a thread';
    end; }

{ TComBufThread }

constructor TComBufThread.Create;

  end;
end;

procedure TComBufThread.Execute;
begin
  { Place thread code here }
  while not Terminated do
