SMSLib中的javax.comm.PortInUseException

我正在尝试使用SMSLib从我的电脑向手机发送短信。我正在使用我的诺基亚5130 GSM手机发送消息，但无法使用。下面是我使用的代码。SMSLib中的javax.comm.PortInUseException

package sms; 
import org.smslib.AGateway; 
import org.smslib.IOutboundMessageNotification; 
import org.smslib.Library; 
import org.smslib.Message.MessageEncodings; 
import org.smslib.OutboundMessage; 
import org.smslib.Service; 
import org.smslib.modem.SerialModemGateway; 

public class SendMessage 
{ 
public void doIt() throws Exception { 
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()); 
SerialModemGateway gateway = new SerialModemGateway("modem.com12", "COM12", 115200, "Nokia", "Nokia 5130 XPressMusic USB Modem"); 


gateway.setInbound(true); 
gateway.setOutbound(true); 
gateway.setSimPin("0000"); 

gateway.setSmscNumber("+919886005444"); 
Service.getInstance().setOutboundMessageNotification(outboundNotification); 
Service.getInstance().addGateway(gateway); 
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("+917829903913", "Sample msg"); 
msg.setEncoding(MessageEncodings.ENC7BIT); 
msg.setSrcPort(0); 
msg.setDstPort(66500); 
Service.getInstance().sendMessage(msg); 

System.out.println(msg); 

System.out.println("Now Sleeping - Hit <enter> to terminate."); 
System.in.read(); 
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(); 
} 
} 
}

这里是我收到的错误消息。请帮忙，因为我对这些没有太多的知识。
