Serial communication in MSP430

Question

I am using MSP430G2553. If I write the following code in energia-0101E0014 doesn't gives any error but in serial monitor data doesn't print but LED blinks perfectly. I know COM port settings and Baud Rate settings and they are correct.

#define LED RED_LED

void setup()
{
    Serial.begin(4800);
    pinMode(LED, OUTPUT);
}

void loop()
{
    Serial.print("Hello world\n");

    digitalWrite(LED, HIGH);
    delay(1000);
    digitalWrite(LED, LOW);
    delay(1000);
}

What is the board you are using? Is it Launchpad? If so, which revision it is? What J3 jumpers configuration do you have? I remember that I had to switch J3 jumper on Launchpad board (rev 1.5) in HW UART position in order to use USCIA0 module. After that I could use /dev/ttyACM0 file to access serial console (via minicom or just stty and echo/cat). — Sam Protsenko
I'm assuming that RED_LED is declared elsewhere? I'm not familiar with Energia — Olivia Stork
