			//DemoSms.java
			

			public class DemoSms
			

			{
			

			public static void main(String args[])
			

			{
			

			SMSClient sc = new SMSClient(1);
			

			sc.sendMessage("MyCellNo","Hello");
			

			}
			

			

			}
			

			//ends here
			

		

			

			#shell file

As we are newbies we are not able to trace where the actual problem is...

We have used this modem in windows env and it runs perfectly..


We have tried configuring minicom also to try to send sms but we have failed in doing so..

We have already put around 20 hours trying to find the error but with no use..

Your help is very much appreciated...

Please help!!!..
