无法使用smslib发送消息

Question

我使用的是Simado调制解调器和丰富的GDT11转串口驱动程序。新连接出现在我的设备管理器>端口列表中。但是，我无法使用smslib发送消息。

我使用的是smslib示例中指定的基本类，但总是会出现一些错误，指出设备没有响应。我添加了轮询参数，因为使用了USB端口，但无济于事。Commtest Utility能够连接到相同的端口，所以我认为端口号不是问题。

堆栈跟踪：

log4j:WARN No appenders could be found for logger (smslib).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
org.smslib.TimeoutException: No response from device.

代码：

public class SendMessage {

public void doIt() throws Exception
{
    SerialModemGateway gateway = new SerialModemGateway("modem.com4", "COM4", 115200, "Simado", "GDT11");
    try {
        OutboundNotification outboundNotification = new OutboundNotification();
        System.out.println("Example: Send message from a serial gsm modem.");
        System.out.println(Library.getLibraryDescription());
        System.out.println("Version: " + Library.getLibraryVersion());
        gateway.setInbound(false);
        gateway.setOutbound(true);
        gateway.setSimPin("0000");
        // Explicit SMSC address set is required for some modems.
        // Below is for VODAFONE GREECE - be sure to set your own!
        gateway.setSmscNumber("+919560734413");
        Service.getInstance().setOutboundMessageNotification(outboundNotification);
        Service.getInstance().addGateway(gateway);
        Service.getInstance().S.SERIAL_NOFLUSH = true;
        Service.getInstance().S.SERIAL_POLLING = true;
        Service.getInstance().S.SERIAL_POLLING_INTERVAL = 200;
        Service.getInstance().startService();
        System.out.println();
        System.out.println("Modem Information:");
        System.out.println("  Manufacturer: " + gateway.getManufacturer());
        System.out.println("  Model: " + gateway.getModel());
        System.out.println("  Serial No: " + gateway.getSerialNo());
        System.out.println("  SIM IMSI: " + gateway.getImsi());
        System.out.println("  Signal Level: " + gateway.getSignalLevel() + " dBm");
        System.out.println("  Battery Level: " + gateway.getBatteryLevel() + "%");
        System.out.println();
        // Send a message synchronously.
        OutboundMessage msg = new OutboundMessage("+918095065000", "Hello from SMSLib!");
        Service.getInstance().sendMessage(msg);
        System.out.println(msg);
    } finally {
        gateway.stopGateway();
        Service.getInstance().stopService();
    }

}

public class OutboundNotification implements IOutboundMessageNotification
{
    public void process(AGateway gateway, OutboundMessage msg)
    {
        System.out.println("Outbound handler called from Gateway: " + gateway.getGatewayId());
        System.out.println(msg);
    }
}

public static void main(String args[])
{
    SendMessage app = new SendMessage();
    try
    {
        app.doIt();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}
}

我解决了这个问题。代码是正确的。显然，使用处于漫游状态的SIM卡并不是个好主意。我换成了本地的SIM卡，信息被发送出去了。

此外，我使用的是USB端口仿真器(Prolific USB-Serial)，由于该仿真器在运行代码时调制解调器无法初始化。

为了解决这个问题，我在服务器启动时运行了初始化命令(AT + CMGF = 1)。
