implementation


{ 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 TWaitThread.UpdateCaption;
    begin
      Form1.Caption := 'Updated in a thread';
    end; }

{ TWaitThread }

constructor TSendThread.Create(SendData: string;IrSocket: TWIrCOMMSocket);
begin
  TxData := SendData;
  FIsFinished := False;
  FIrSocket := IrSocket;
  inherited Create(False);
end;


procedure TSendThread.Execute;
begin
  Synchronize(ExecuteEx);
end;

procedure TSendThread.ExecuteEx;
begin
  Screen.Cursor := crAppStart;
  //-------------------------------
  Try
     FIrSocket.SendStr(TxData + #13);
  Finally
     Screen.Cursor := crDefault;
     FIsFinished := True;
  End;
  //-------------------------------
end;
