OVERVIEW

     The GSM library is written in C++ and uses the latest C++
     features: namespaces, exceptions, the standard template library.

     The actual library source code is in the gsmlib subdirectory of
     this distribution. The following modules are available:

     gsm_alloca.h      OS-specific alloca defines
     gsm_at.h          Utility classes for AT command sequence handling
     gsm_error.h       Error codes and error handling functions
     gsm_event.h       Event handler interface
     gsm_me_ta.h       Mobile Equipment/Terminal Adapter and SMS functions
                       (ETSI GSM 07.07 and 07.05)
     gsm_parser.h      Parser to parse MA/TA result strings
     gsm_phonebook.h   Phonebook management functions
     gsm_port.h        Abstract port definition
     gsm_sms.h         SMS functions (ETSI GSM 07.05)
     gsm_sms_codec.h   Coder and Encoder for SMS TPDUs
     gsm_sms_store.h   SMS functions, SMS store (ETSI GSM 07.05)
     gsm_sorted_phonebook.h Alphabetically sorted phonebook
                            (residing in files or in the ME)
     gsm_sorted_sms_store.h Sorted SMS store
			    (sorted by address, time or type)
                            (residing in files or in the ME)
     gsm_unix_serial.h UNIX serial port implementation
     gsm_util.h        Various utilities


REQUIREMENTS

     I have used egcs-1.1.2 and libstdc++.so.2.8.0 for compiling the
     library and all programs. Older probably don't work because of
     missing features.


AVAILABLE DOCUMENTATION

     If you want to do your own programming using the GSM library please
     refer to the extensively documented header files or to the example
     programs in the test or apps subdirectory.

     I have used the following documentation to develop this software:

       gts_gsm_02.30_v5.2.0.pdf
       gts_gsm_03.40_v5.3.0.pdf
       gts_gsm_04.11_v5.1.0.pdf
       gts_gsm_02.82_v5.0.0.pdf
       gts_gsm_03.41_v5.2.0.pdf
       gts_gsm_07.05_v5.3.0.pdf
       gts_gsm_03.38_v5.3.0.pdf
       gts_gsm_04.08_v5.1.0.pdf
       gts_gsm_07.07_v5.0.0.pdf

    Due to copyright reasons I cannot include this documentation in
    this distribution. You can download it from the ETSI website
    (www.etsi.org) for free, though.


COMPILATION

    The code is automatically compiled without debugging code enabled
    (mostly assert()'s). 

     If there are any problems you can generate a debug version
     by issuing

       CXXFLAGS="-g" ./configure --disable-shared

     To switch on asserts and additional debugging output change the line

       CXXFLAGS="-DNEBUG $CXXFLAGS"

     in configure.in do

       dnl CXXFLAGS="-DNEBUG $CXXFLAGS"

     Then regenerate configure by executing autoconf.

     You must use at least gcc-2.95.2 to compile gsmlib successfully.


TESTS

    The tests directory contains a number of software tests. Two kinds 
    of test programs are provided: Those, that run without a mobile
    phone and those that require a mobile phone to be connected to a
    serial port.

    No access to mobile phone needed:
    runparser.sh      Test the parser for AT responses
    runsms.sh         Test SMS message encoding and decoding routines
    runspb.sh         Test sorted phonebook module
    runssms.sh        Test sorted SMS store module

    Give mobile phone device as argument:
    testsms2          Manipulate SMS store in the mobile phone (read/write)
    testgsmlib        Test the gsm_me_ta module (readonly)
    testpb            Dump all phonebooks in the mobile phone to the stdout
                      (readonly)
    testpb2           Manipulate phonebook in the mobile phone (read/write)

    The tests that do not require a mobile phone can be executed by
    issuing "make check" in the tests subdirectory. The others must be 
    invoked manually. WARNING: These tests alter the contents of the
    mobile phone's phonebook or SMS message memory!!! Make sure, that
    you understand what the test does and be prepared for loss of data in
    the mobile phone.

HINTS

    - By default gsmlib is compiled with NDEBUG set. There are lots
      of assert()s all over the library that may help to find problems
      in programs that use the library. Disable NDEBUG to get best
      debugging support.

CUSTOM BACKENDS

    gsmlib now allows custom backends to be defined for sorted phonebooks
    and sorted SMS stores. This can be used to store phonebook entries in
    relational databases or LDAP servers. The interfaces are defined in
    gsm_sorted_phonebook_base.h and gsm_sorted_sms_store_base.h,
    respectively.

    To register a custom backend (eg. for sorted phonebooks) follow
    these steps:

    1. Define a subclass of CustomPhonebookFactory.

    2. Define a static initializer class in your module that uses the
       interface CustomPhonebookRegistry::registerCustomPhonebookFactory()
       to make your custom backend available.

    3. Link your module to any application that should use your custom 
       backend. The gsmpb and gsmsmsstore programs are prepared to use the
       CustomPhonebookRegistry class to obtain your custom backend
       objects.

Something went wrong with that request. Please try again.
