How To Test for Lost Serial Port?

Processing Electronics (Arduino, etc.)

I managed to get it to work. (based on info from previous comments)

Here is the code for anyone to refer in future.

import processing.serial.*;

Serial myPort;
String currentPort;

void setup(){
  myPort = new Serial(this, Serial.list()[1], 9600);
  currentPort=Serial.list()[1]; // Save current port
}

void draw(){
  if(serialPortCheck()==true){
    println("com port found");
  }else{
    println("com port lost");
  }
  serialReadData();
}

boolean serialPortCheck(){
  boolean connected = false;
  String[] str = Serial.list(); // Get the current list of available ports
  for(int i=0; i<str.length; i++){
    //println("com:"+currentPort+"    str[i]:"+str[i]);
    if(currentPort.equals(str[i])==true){ //check if currentPort is still in the list of comPorts
      connected=true;   // com port found so still connected                   
      break;
    }
  }  
  return connected;
}

void serialReadData(){
  if(myPort.available()>0){
    println(myPort.readString());
  }
}
