[En-Nut-Discussion] Translation of \n to \r\n

[Dusan Ferbas]

Hi Ajit,

if you want to reduce code size, you can use following, simpler way:

         uart = fopen("uart0", "r+b");                   //select binary mode

         //following is set automatically when binary mode is selected
         //_ioctl(_fileno(uart), UART_SETCOOKEDMODE, &cooked_mode);
