我一直在搜索这个问题;我读过关于rxtx，javacom，smslib等。我找到了几篇文章，但我真的无法理解它，因为我是初学者。
实际上，我在这里找到了一些可以发送短信的好文章，但问题是我想阅读传入的短信，然后删除它。
我发现我可以通过使用AT+CMGR，AT+CMGL从这里做到这一点
我需要在Java中使用什么语法来尝试AT+CMGR和AT+CMGL来阅读短信并至少打印它？
我已经使用以下代码成功检查哪个端口已准备就绪：
package anothersms;
import gnu.io.*;
import java.util.Enumeration;
public class CommPortTest {
public static void main(String[] args) {
System.out.println("Program Started!!!");
CommPortIdentifier serialPortId;
Enumeration enumComm;
enumComm = CommPortIdentifier.getPortIdentifiers();
while(enumComm.hasMoreElements())
{
serialPortId = (CommPortIdentifier)enumComm.nextElement();
if(serialPortId.getPortType() == CommPortIdentifier.PORT_SERIAL)
{
System.out.println(serialPortId.getName());
}
}
System.out.println("Program Finished Sucessfully");
}
}
经过很长的路要设置DLL等，我发现这有效，但我仍然几乎不明白它。
我得到读取和删除消息的代码。但它不使用命令，它使用 smslib ，但仍然足够简单，所以我并没有真正混淆。
我从这里获得代码，代码甚至使我们能够侦听是否有传入消息并通知我们。
此外，我添加了一些代码以在阅读后删除传入的消息。这是代码
