Sending MaxMSP data to Arduino (4 bit data)

I am using 2 Arduinos with MaxMSP.

1. [Arduino #1] -----> sends data to [MaxMSP]

2. [MaxMSP] (with thresholds and calculations) -----> [Arduino #2]
The first part is working fine. But, I am having trouble sending the data to Arduino #2 from MaxMSP.
It needs to spit out 4-byte data.

When I test with the patch below, it did not show multiple data into a string. And also it can only receive the data up to 255. But, my data is minimum 1000 and maximum up to 18000. So I am thinking that I must be missing something. The above Max Patch is Arduino #1 sending data to MaxMSP and its working. I just need to reverse this mechanism to apply it on Arduino #2, but I'm lost here.

const int led = 13; //pin 13 for board led on uno

int value;

void setup() {
//open digital pin for board led
pinMode(led,OUTPUT);

//open the serial port for reading
Serial.begin (115200);
}

void loop() {
  //checks to see if there is information on the serial port or not

  if (Serial.available()) {
    //max is sending packets of information
    //space is a separator so we need to store each value

    value = Serial.read();

    Serial.println(value);
  }//end serial
}

Any help would be truly appreciated!
