ESP8266 Initial Connection Issue: Reset Required for Message Sending

[gmm932]

When I first connect the ESP8266 to the computer, I run my demo and cannot write messages, but if I press the ESP8266 RST reset button once and run the demo again, I can send messages. I don't know why, and Arduino tools don't have this problem.

this is my demo.

const { SerialPort } = require('serialport')

const portName = 'COM3'; 
const baudRate = 115200; 
const port = new SerialPort({ path: portName, baudRate: baudRate })

setInterval(function () {
    port.write('D1_300_500_1\n', function(err) {
        if (err) {
            return console.log('Error on write: ', err.message)
        }
        console.log('message written')

        // port.close(function (err) {
        //     console.log(err)
        // })
    })
},1000)


let receivedData = '';
port.on('data', (data) => {
    receivedData += data.toString();
    if (receivedData.includes('\n')) {
        const cleanedData = receivedData.replace(/[\r\n]/g, "");
        receivedData = '';
        console.log(cleanedData)
    }
});
// Open errors will be emitted as an error event
port.on('error', function(err) {
    console.log('Error: ', err.message)
})

I tried to use @serialport/parser-ready but it didn't work.
