No output in connected console

[tomasz90]

Here is my sketch:

#include <Arduino.h>
#include "AsyncTelnetSerial.h"

#define BAUD_RATE 115200

AsyncTelnetSerial telnetSerial(&Serial);

void setup() {
    Serial.begin(BAUD_RATE);
    WiFi.mode(WIFI_STA);
    WiFi.begin(WIFI_SSID, WIFI_PASS);
    WiFi.setAutoReconnect(true);
    while (WiFi.waitForConnectResult() != WL_CONNECTED) {
        delay(2000);
        ESP.restart();
    }
    telnetSerial.begin();
}

void loop() {
    Serial.print("Hello World");
    delay(1000);
}

Despite being able to connect to my device, I don't see any output... I would like to see "hellow world", Is there any issue?
