Sending command to a mobile phone blugged into a pc to send an sms

Question

hi.
i am new to this field, but i heard of "at command" that are helpful to control the mobile phone from a pc. And Java supports this...
this is the case:
1- a mobile with a valid sim card is connected via USB with the pc.
2- an application is running at the pc (java application)
on this application we need to add a module/class that sends command "at command" to our connected mobie with 2 parameters:
1- the phone number
2- the message
MyClass.sendViaMobile("[phone]", "we want to inform you that u got the help :-)");what i need is how to start this, what do i need to know,and what api's i need to use
regards,

hi mlk
i found the rxtx api, but i got now a question,
how to connect to a usb port?
it seems that it is easy to deal with com port or serial port, but until this moment usb didnt work,
in my case, the mobile is connected via usb port.
this a code that uses the RXTX API, whaere do i need to modify to connect using usb?
*note, the following code is written by someone else, it works via com port...
//     SendMessage.java - Sample application.
//          This application shows you the basic procedure needed for sending
//          an SMS message from your GSM device.
//     Include the necessary package.;c:\classpath\smslib.jar;c:\classpath\comm.jar
package examples;
import org.smslib.*;
class SendMessage
     public static void main(String[] args)
          // Define the CService object. The parameters show the Comm Port used, the Baudrate,
          // the Manufacturer and Model strings. Manufacturer and Model strings define which of
          // the available AT Handlers will be used.
          CService srv = new CService("COM1", 19200, "Nokia", "6630");
          System.out.println();
          System.out.println("SendMessage(): Send a message.");
          System.out.println("  Using " + srv._name + " " + srv._version);
          System.out.println();
          try
               // If the GSM device is PIN protected, enter the PIN here.
               // PIN information will be used only when the GSM device reports that it needs
               // a PIN in order to continue.
               srv.setSimPin("0000");
               // Normally, you would want to set the SMSC number to blank. GSM devices
               // get the SMSC number information from their SIM card.
               srv.setSmscNumber("");
               // OK, let connect and see what happens... Exceptions may be thrown here!
               srv.connect();
               // Lets get info about the GSM device...
               System.out.println("Mobile Device Information: ");
               System.out.println("     Manufacturer  : " + srv.getDeviceInfo().getManufacturer());
               System.out.println("     Model         : " + srv.getDeviceInfo().getModel());
               System.out.println("     Serial No     : " + srv.getDeviceInfo().getSerialNo());
               System.out.println("     IMSI          : " + srv.getDeviceInfo().getImsi());
               System.out.println("     S/W Version   : " + srv.getDeviceInfo().getSwVersion());
               System.out.println("     Battery Level : " + srv.getDeviceInfo().getBatteryLevel() + "%");
               System.out.println("     Signal Level  : " + srv.getDeviceInfo().getSignalLevel() + "%");
               // Lets create a message for dispatch.
               // A message needs the recipient's number and the text. Recipient's number should always
               // be defined in international format.
               IOutgoingMessage msg = new COutgoingMessage("+5550000", "Message from SMSLib for Java.");
               // Set the message encoding.
               // We can use 7bit, 8bit and Unicode. 7bit should be enough for most cases. Unicode
               // is necessary for Far-East countries.
               msg.setMessageEncoding(IMessage.MESSAGE_ENCODING_7BIT);
               // Do we require a Delivery Status Report?
               msg.setStatusReport(true);
               // We can also define the validity period.
               // Validity period is always defined in hours.
               // The following statement sets the validity period to 8 hours.
               msg.setValidityPeriod(8);
               // Do we require a flash SMS? A flash SMS appears immediately on recipient's phone.
               // Sometimes its called a forced SMS. Its kind of rude, so be careful!
               // Keep in mind that flash messages are not supported by all handsets.
               // msg.setFlashSms(true);
               // Some special applications are "listening" for messages on specific ports.
               // The following statements set the Source and Destination port.
               // They should always be used in pairs!!!
               // Source and Destination ports are defined as 16bit ints in the message
               // header.
                msg.setSourcePort(10000);
                msg.setDestinationPort(50000);
               // Ok, finished with the message parameters, now send it!
               // If we have many messages to send, we could also construct a LinkedList with
               // many COutgoingMessage objects and pass it to srv.sendMessage().
               srv.sendMessage(msg);
               // Disconnect - Don't forget to disconnect!
               srv.disconnect();
          catch (Exception e)
               e.printStackTrace();
          System.exit(0);
