Changelog for SCMxx:

0.6.0 (2002-04-05)
    THIS IS NOT THE C++ VERSION AS PERVIOUSLY STATED AS GOAL ON THE WEBSITE!
    !!!!! Syntax changed !!!!!
    all timezone values in the time fields can now be decoded correctly
    added debian_with_scmxx.bmp to examples dir
    various other code cleanups:
	rewrite of checkslots and info methods and some others
	removed com2_mytty method
	giving transfer methods the proper parameters to not use global variables
	    anymore
	removing most of the global variables
	unified some global variables to bitvalues of a local variable or structs
	better usage of C pointers and some dynamic memory allocation
    new (requested) parameter --version that prints the version number
    multiple file upload support (adding only)

    --pipe support for getting sms (indirect, too) and files
    --pipe and --file are now independent of each other

0.5.16.2 (2002-03-29)
    moved "File transfer..." message to be displayed after reading the file
    fixed bug in file read-in for file transfer (3rd package and above)
    print message when input comes from a tty (and how to finish it)
    on reading for file transfer, only read second block if first is full
	(needed, so you do not have to close input from a tty twice)

0.5.16.1 (2002-03-28)
    changed some variable name to be C89 compliant (see stdin(3))
	thanks to Klaus Klein for pointing at this

    new parameter --reset which resets the phone if it does not respond after
	a user-aborted file transfer
    lots of code cleanups
    changed the read_mytty method to be more cleaner and work with raw mode
    added read_mytty_limited to read to a boundry instead of a lines end
    change sending code (sms and files) to makes use of raw mode, so data is
	really only sent, when no error occurs
    added is_number method to be more specific than atoi
    added "all" to file deleting and getting
    added pipe ability to file getting method
    do not try to decode unsupported PDU types

    fix crash when build with optimizations
    fix include of present CFLAGS env
    decode some known sms user data header fields and display this information
    show 8bit and 16bit sms messages as hexstring (instead of nothing)
  addon:
    changed hexstr2int to not used atoi anymore (can give segfaults at runtime)

0.5.13    
    fix phonebook text field length check for the new casted characters
    we now use autoconf and autoheader to create the build files
	config.h and Makefile (thanks to Michael Banck <mbanck@gmx.net>)

    change sms input definition: greek character must be masked with a prepended '\'
	which enables all greek characters instead of only the non-coliding ones
    renamed device.h to config.h
    change config.h to defines and declare variables in common.h and init them
	in scmxx.c:main by calling the set methods

0.5.10
    fix sms '@' bug in sending (thanks to Nuno Miguel Fernandes Sucena Almeida <slug@aeminium.org>)

0.5.9
    changed from strcmp to strcasecmp for "cme error: invalid index" check
	in pbook code
    Merged the variable baudrate patches from Klaus Klein <kleink@reziprozitaet.de>

0.5.8
    added "" around date in at command (bug report)
    7Bit-GSM message with user data header (like multipart text messages)

0.5.7
    changed the serial parameters (I hope they work now).

0.5.6
    fix the previously added VCF support

0.5.5
    add VCF support for phones newer that the 35-series

0.5.4
    fix OA if length of OA is wrongly created by SMSC (cut trailing F)
    moving some routines to smspdu.c
    code cleanup done by using -Wall
    use TCIOFLUSH instead of TCIFLUSH and do that before every ATZ retry
    removed fstat for files: This should now work for all
	kernel versions but uses a somewhat odd method. I
	hope this does not break it for anyone.

0.5.3
    fixed SMSC number display cut (last digit)
    fixed DCS decoding (11xxxxxx)
    decoding of characters from the GSM extension table
    typo in open_myFile_rw [stdin/stdout]
    when phone not answers to ATZ resend the command up to 2 times
    do not close stdout/file when receiving SMS directly (don't throw this
	file descriptor away)
    check the size of the created user data to catch the case that some
	characters need 14bits (or more) instead of 7bits (GSM extension tables)
    remove fstat for in SMS method because it does not work for kernel 2.4
	replaced by another method which does not work for files, though
        => files and stdin are not possible with kernel 2.4, only kernel 2.2
    new feature --pipe: on direct receiving the SMS can _additionally_ be
	processed by a program that gets the SMS on stdin

0.5.2
    8bit SMS are not displayed any more: it is only binary junk anyway
	this remains until SMS support is complete
    SMS can now be received directly by setting "-gS --direct"
    SMS output shows more decoding details
    GMT offset display is omitted when value unknown
    changed output when sending files (not so hard on the eye with large files)
    fixed display bug with reading of uneven length of SMSC number
    fully decode DCS field (displayed)
    changed 7bit detection in DCS field (more messages can be decoded!)
    find all 8bit and unicode messages (not decoded, yet)
    extract and show user data header
    decode when origin is alphanumeric (Thnx Fabio Coatti for the hint)
    fixing international number to do it right now
    GMT offset display looks at MSB to differ - and +

0.5.1
    fixed bug with null-byte in message left out => junk
    fixed bug when trying to send 158-160 characters
    SMS number check and error catching on sending
    show SMS-slot on output to make deleting easier
    incomplete phonebook files can now be sent
	only fixed the entry displayed and the error message
    fixed segfaults on syntactically wrong phonebook file lines
    make add_at_command handle all cases and change all occurences
    made many string sizes one char larger and changed code to adopt new length
    remove/replace some unnessary variables
    delete code that does not get used anymore
    add environment variable SCMXX_TTY to set device in yet another way
	to show which one is used, the device is now printed

0.5
    added parameter --pin and made pin handling transparent to functions
	=> FD is now writable
    added signal quality info to info output
    the SMSC can now be set with --set-smsc -n <number>
    fixed bug in sending piped files (unsigned char instead of char)
    fixed bug in sending piped sms (memset missing)
    fixed pbook routines for those bugs (just in case)

0.4.6
    fixed vcs auto detection which broke in 0.4.5
    the hexstring of 8bit messages is now converted to bytes
    fixed segmentation fault when no sms number was given
    SMS text can now be specified in a file or stdin

0.4.5
    again, bug fixes in character conversion:
	 is fixd,
	\n can now be used as newline in SMS text on command line,
	Euro symbol phone error compensation (an e as next char needed) but
	not for vCals
    changed behaviour of -v and -q to be more flexible
    autodetection of available slots instead of hardcoding
	=> allowing all Siemens phones by default but display a warning

0.4.4
    a new Makefile from Manfred Fandel
    a note from Andreas Wegmann: the phone does not use RTS/CTS handshake
	and it does not work with self-build cables when set
	-> I disabled it but I could not test it. If it makes trouble, just
	   comment out the line in common.c
    the argument to the "--vcal" parameter is now obsolete on sending.
	if it is omitted, auto detection finds the next free slot
    the letter size of phonebooks does not matter anymore

0.4.3
    SMS of type SMS-SUBMIT can now be read from the phone
	the output was adjusted
    the message part of an 8bit message does not get converted.
    the argument of parameter for bitmap and midi is now optional
	like for SMS, they have the default of 0
    thanks to Manfred Fandel for tips for making version number
	handling much easier :-)

0.4.2
    stdin now possible with bitmap, midi and vcs

0.4.1
    fixed bug which made overwriting existing file (by accident???) possible
    added PDU decoding routine
    fixed iso2gsm to only allow GSM chartacters very strictly
    stdin/stdout are now usable instead of a file
    added hexstr2int routine and changed other routines to use it
    added stdout/stdin support
    add SMS getting routine (slot or status)
	this only includes status read and unread because they are always
	of type SMS-DELIVER. sent, unsent and all will follow
    added SMS deleting routine (slot only)
    removed parameter --sms-slot which should be and is now an option
    of --sms (also take a look at the file BUGS!!!)

0.4
    tweaked phonebook support to access all Siemens specific phonebooks, too
    the last dialed memory can now also be deleted
    storing and sending of SMS is now possible (actually functioning totally equal) :-))
	options: only text and number (the rest are reasonable defaults)
	SMS length of 160 chars is supported (7bit encoding)
	non-GSM chars are ignored
    sending of stored SMS supported (SMS slot must be known)
    fixed serial support for upload of Bitmap, Midi and vCalendar
    C35i and M35i are now recognized (Bitmap size might be different from S35i)

0.3.1
    phonebook file format was changed a bit (includes empty entries now)
    sending and deleting of phonebooks possible now
	(not single entries, only whole phonebook)
	be aware that it will delete without further asking!!!
    added iso2gsm routine	
	three greek characters cannot be converted on sending
	(this will fit the need for unicode)
    add GSM character set for reference
    fixed gsm2iso routine to handle ALL characters now (correctly)

0.3
    added reading all possible phonebooks (sanity checks does the phone)
	and saving them to a file
	Note: File format is incompatible with ln-s25 (but can easily
	      made compatible by hand). I saw no reason for the 3rd field.
    changed info output to show possible phonebooks and file slots
    changed read routine to handle @ conversion problem
    added gsm2iso routine for character conversion (should handle all characters)
	(does anyone has a complete GSM char table?)

0.2.2
    change file access routines for sending files (same as getting now)
    added "--info" paramater and routine
    added "--set-time" parameter and routine
    change help text a little bit
    serial cable connections do not work properly, yet.
    added Makefile (not optimal though)

0.2.1
    receive bitmap, midi and vcs

0.2
    first public release
    detect type of mobile phone
    delete bitmap, midi and vcs
    send bitmap, midi and vcs
