// SMS Transceiver// SMS Transceiver is a tool for sending and receiving SMS via a//   serial connection between PC and a mobile phone. It establish//   on the basis of a serial line (or IrDA) connection a AT command based//   communication for sending and receiving SMS and SMS-based e-Mails.//// file: SMS.java// uses: SMSTools.java, Msg.java, Port.java//// This program uses the javax.comm Service from Sun to transfer data via the// serial PC port. Tested with JBuilder 6, JDK 1.3.1 on Windows 2000 and// with Nokia 6210 on port COM 1 in German D1 GSM net. Tested also via IrDA// connection with IrCOMM2k and Siemens SL55 (some of the features are not// available on the SL55).//// Third party tested with Siemens ME45 and Siemens S45, Windows XP and Unix.//// The AT commands for mobile telephone are specified in the ETSI standards://   TS 27.005 Data Circuit terminating Equipment (DTE - DCE) interface for//             Short Message Service (SMS) and Cell Broadcast Service (CBS)//   TS 07.07  AT command set for GSM Mobile Equipment (ME)//   TS 27.007 AT command set for 3G User Equipment (UE)//   TS 23.040 coding of PDUs//// Remarks: * Before starting this programm you have to adopt SMSDIALNO, EMAILDIALNO,//            EMAILADR to your personal values.//          * On some GSM networks you have to switch on the SMS to email option first.//            This could be (on some networks) done with a SMS including the command OPEN to the SMSC.//          * It is a good practice to test all AT command to a mobile first with a terminal programm.//          * This tool works only with data coding scheme = 00 (=standard GSM Alphabet).//          * Some SMSC uses non ETSI conform codings or unusual coding parameters,//            this could cause problems with the decoding of the PDUs.//          * SMS Transceifer work in PDU mode of the mobile phone not in text mode. By//            the way text mode is quite simple, but there are many phone which don't//            support it, because its an optional feature.//          * Useful tool for PDU analysing : pduspy.exe (use e.g. Google for retrieving it)//          * Some GSM networks supports for SMS a confirmation of receive. In the//            German D1 GSM net this could be done by *T# at the beginning of the SMS.//          * Statements for debuging are marked by "for debuging".//          * For SMS only you don't need EMAILDIALNO and EMAILADR. This email stuff should//            demonstrate the possibility to send Internet emails from a SMS device.//          * The timing for sending and receiving data over the RS232 is on some//            PC or Unix hardware sometimes quite critical. There are also some mobile phones//            who sends the individual bytes of the response quite irregular, sometimes with//            quite big breks between the individual bytes. The critical places for this//            data communication are marked with [Timing].//          * The "create PDUs functionality" can be used to generate predefined PDU which can//            be send via a simple microcontroller application with AT-commands to a mobile phone.//// Ideas for the next versions:   * UCS2 support (difficult, quite much work)//                                * MMS support (only if a AT command interface is specified by ETSI)//                                * version for PIC microcontrollers (much work, difficult interoperability))//// Warning: This programm deletes all the SMS stored in the mobile phone.//// Release Procedure:   1. find and solve all critical points marked by  "???"//                      2. Test all separate SMS Transceiver functionalities from GUI//                      3. Anonymisize moile phone number and email adress//                      4.
