7 Segment Serial Display Using Serial Communication

hello everyone,
i have bought 7 segment serial display sparkfun.  http://www.sparkfun.com/products/9764  wanted use serial communication control this.  have seen examples using software serial library in arduino 1.0, prefer use serial.print (or write, don't know one) control this.  here current code. 

code: [select]


// 7 segment sketch

void setup() {
  serial.begin(9600);  // start serial communication
}

void loop() {
  serial.print(1024);
  delay(1000);
  serial.print(4201);
  delay(1000);
}


it comes out 1420, 4102.  help?

looks had unintended character sent out, causing data wrapped around.
maybe send out 0's in void setup start, send 4 bytes.
