OseppBlock displaying boxes on serial monitor

Using Arduino Programming Questions
#1

Does anyone know why oseppBlock is displaying these empty text boxes instead of “Jay”? It is on com3 115200.

void setup() {

Serial.begin(9600);
}

void loop() {
Serial.println(“Jay”);
delay(1000);
}

#2

It is on com3 115200.

 Serial.begin(9600);

Don’t those baud rate numbers need to match?
