How do I see sensor's response through Serial Monitor 'mySerial'?

You have to add something like this to the loop() to transfer the command string from the serial console to the device om mySerial:

if (Serial.available() > 0) {
   mySerial.write(Serial.read());
}

The carriage return and line feed are delivered automatically when the appropriate setting is chosen in the serial console.
