}
in the above code it shows no error while running its no message is delivered to the mobile , i saw the thread http://javamix.wordpress.com/2009/01/21/sending-sms-using-serialport-communication-api/ …..can u send the complete code to send sms or can u alter the my code to send sms sucessfully , its very urgent for me ,thank god to ur post.

hai vijay
more over while saving your code it shows a error “some character could not be mapped usingcp1252 character encoding either change the encoding or remove the code which are not supported by cph1252″ so i i changed the code
char[] s5={‘”‘,’9′,’3′,’4′,’6′,’4′,’6′,’2′,’1′,’6′,’5′,’”‘}
}; TO
private static char[] hexDigits = { ’0′, ’1′, ’2′, ’3′, ’4′, ’5′, ’6′, ’7′,
’8′, ’9′, ‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’
}; now i can able to save , similarly can you tell me the what is the necessary of the s6=”32″,whether i have to change this value finally i gave string values
String s1=”AT”;
String s2=”\r\n”;
String s3=”AT+CMGF=1″;
String s4=”AT+CMGS=\”9965844325\”";
char[] hexDigits = { ’0′, ’1′, ’2′, ’3′, ’4′, ’5′, ’6′, ’7′,
’8′, ’9′, ‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’
};
String s6=”32″;
while running the program console the output like this
Set default port to COM1
Found port: COM1
inside initwriteport
–1–
–2–
–3–
–4–
–5–
Read: AT
OK
AT+CMGF=1
OK
Read:
AT+CMGS=”9965844325″
Read:
> first sms send by a
Read: run ram!
> 32send by a
but message is not delivered to my number 9965844325…and also you have included the package package sms; whether i need to execute this code …i am expecting a quick reply from mail id is (“arunram.prf@gmail.com”)

Hi,
Nice to see a Complete program. But A Small Problem. I connected my Nokia 5230. then it reported as COM5. but no message is delivered. No Message in the out box too. Can you help about this issue or suggest me a handset/ data card which works successfully.
