我正在开发一个 Java 应用程序来获取电话号码。我正在使用 USRobotics 5639 调制解调器（支持来电显示），并且我的电话公司确实提供来电显示服务。当我使用超级终端时，我得到了呼叫的号码、时间和日期：

ATZ
OK
AT+VCID= 1
OK
 这就是我目前所拥有的：

        catch(IOException e)
        {
            e.printStackTrace();
        }
    }
}

我缺少什么来获取主叫号码的所有信息？

在您的while(!read)循环中，您可以将其更改为while(true)循环，因为您希望在初始传输后继续接收数据。实际的数据提取必须由您负责，特别是在NMBR=标签之后。我还清理了您的一些代码，以便于复制粘贴：
