public class smsModem

    private static  LinkedList<COutgoingMessage> msgList = new LinkedList<COutgoingMessage>();

    private static int baudRate=0;
    private static CService srv;
    private static boolean isSending=false;
    private static   void  testAndSetCom()
        /**
        Try to find out which com port is used by modem and the work baudrate.
        */
        {
        CommPortIdentifier portId;
        Enumeration portList;
        //int bauds[] = { 9600, 19200, 38400, 115200 };
        int bauds[]={38400, 115200};
        portList = CommPortIdentifier.getPortIdentifiers();
        while (portList.hasMoreElements())
            {
            portId = (CommPortIdentifier) portList.nextElement();
            System.out.println("PORTID:"+portId);
            if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL)
                {
                System.out.println("Found port: " + portId.getName());
                for (int i = 0; i < bauds.len
