Hi, I am trying to program 89V51RD2 micro controller using flash magic. When it asked to reset the device into ISP mode now, I pressed the reset switch on the development board but the message box still exists and the console shows "Attempting to Connect". I am using USB to Serial port connector and the cable is perfectly OK as I have validated loop back test with it.
Could you please help me on this.
