Sending SMS using serialport in Java

before going to execute this program read here  <a href="http://javamix.wordpress.com/2009/03/30/installing-comport-api-in-windows/">how to install comport api for windows</a>

/*  this is the program used to send the message from javaprogram to the mobile phone */

/*

Note :- before using this porogram  first read the post "serialport communication using Java" by me in this blog.

package sms; // it is my own package
import java.io.*;
import java.util.*;
