java 描述语言

// Node.js program to demonstrate the
// readStream.setRawMode() method

// Importing dgram module
var dgram = require('dgram');

// Creating and initializing client
// and server socket
var client = dgram.createSocket("udp4");
var server = dgram.createSocket("udp4");

// Catching the message event
server.on("message", function (msg) {

    // Creating and initializing a
    // ReadStream object
    let ReadStream = process.stdin;

    // Setting the read stream Raw mode
    // by using setRawMode() method
    ReadStream.setRawMode(false);

    // Checking if it is configured or not
    // by using isRaw() method
    const status = ReadStream.isRaw;

    // Displaying the result
    if (status)
        process.stdout.write(msg + "configured" + "\n");
    else
        process.stdout.write(msg + "not configured" + "\n");

    // Exiting process
    process.exit();
})

    // Binding server with port
    .bind(1234, () => {

输出:

It is not configured
