Serial Connection ATMEGA328p - c

Question

I wrote up a function to connect via UART and print a string for debugging purposes. But my logic does not add up somehow... I see the line "Random Number" printed in the console but blazingly fast... no matter what I add for a _delay_ms value, it is not usable. Did I miss out on anything?
Why is my delay function not having any influence on the output on the serial terminal?
void initUSART(void) {
#define BAUDRATE ((F_CPU) / (BAUD * 8UL)-1) // Set Baud Rate Value for UBRR
// Set register
UBRR0H = (BAUDRATE >> 8);
UBRR0L = BAUDRATE;
UCSR0A |= (1 << U2X0);
// Enable USART transmitter and receiver
UCSR0B = (1 << TXEN0) | (1 << RXEN0);
// Set 8 data bits and 1 stop bit
UCSR0C = (1 << UCSZ01) | (1 << UCSZ00);
}
void transmitByte(uint8_t data) {
// Wait for empty transmit buffer
loop_until_bit_is_set(UCSR0A, UDRE0);
UDR0 = data;
}
void printString(const char myString[]) {
uint8_t i = 0;
while (myString[i]) {
transmitByte(myString[i]);
i++;
}
}
int main(void)
{
setup();
randomSeed(adcRead(0));
while (1)
{
printString("Random Number:\n");
_delay_ms(100000);
}
return (0);
}
When I use \r\nat the end of the string, the output gets really strange:
When I try this test code everything works as expected, the LED blinks every second. I really don't see where the difference is, as it is the same function.

// ------ Event loop ------ //
while (1) {
PORTB = 0b00000001; /* Turn on first LED bit/pin in PORTB */
_delay_ms(1000); /* wait */
PORTB = 0b00000000; /* Turn off all B pins, including LED */
_delay_ms(1000); /* wait */
} /* End event loop */
return 0; /* This line is never reached */
}
