static port_setting_struct const NVRAM_EF_PORT_SETTING_DEFAULT[]=
{
    {
    #if defined(__ONLY_ONE_UART__) || defined(__MMI_DUAL_SIM__)
        4,//99, /* tst-ps uses uart_null(value is 99 (0x63)) */ //zengxing
        /* 4 为usb port, 默认为99*/
        0, /* APP uses uart_port1 (value is 0) */
    #elif defined (WISDOM_MMI)
