Hello, I have two Linux machine. On one machine SMSLib application i.e. SendMessage.java and CommTest.java utility is working perfectly fine and CommTest utility is detecting port perfectly fine, But on second machine It is not working with same modem. CommTest utility is also not able to detect the port to which it is connected. I did same configuration on both machine. I am using rxtx library on both machine I also tried with comm library, but problem is same.
Please help me. what may be the problem. why such problem is coming. Thanks for reply.
