sending sms using serialport communication API

before going to execute this program read how to install comport api for windows

/*  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.*;
import javax.comm.*;          //for accessing serialport
