* Revision 1.30 2007/01/05 04:23:58 tobiasb
* Made isdnrep and isdnrate buildable under cygwin. See ChangeLog for details.
*
* Revision 1.29 2004/09/05 22:04:56 tobiasb
* New parameter file entry "ignoreUPD" for suppressing "Unexpected
* discrimator (...)" messages, demanded by Günther J. Niederwimmer
* on the suse-isdn mailing list.
*
* Revision 1.28 2004/01/28 14:27:46 tobiasb
* Second step in restricting fds at isdnlog restart and script starting.
* The fd limit is now taken from getrlimit() instead of NR_OPEN.
* Close_Fds(first) which tries to close all possible fds is generally
* built in but the execution must be requested with "closefds=yes" in
* the parameterfile otherwise the isdnlog behaviour remains unchanged.
*
* Revision 1.27 2004/01/26 15:20:08 tobiasb
* First step to close all unnecessary open file descriptors before
* starting a start script as reaction to a call. The same applies to the
* restart of isdnlog using SIGHUP. Till now each restart increases the
* number of used fds.
* For now the modifications are inactive by default. They can be enabled
* by adding the line "DEFS += -DFD_AT_EXEC_MODE=1" to ../Makefile.in.
* The next isdnlog (4.68) will have this enabled per default.
* The upper limit for fd numbers is taken from NR_OPEN in <linux/limits.h>.
* If there is a smarter way to access this limit, please let me know.
* Another approach would be to set the close-on-exec flag on each fd
* directly after it is opened. This would require more extensive changes.
* I'd like to thank Jan Bernhardt for discovering this problem.
*
* Revision 1.26 2003/08/26 19:46:12 tobiasb
* isdnlog-4.66:
* - Added support for AVM B1 (with layer 2 d-channel trace) in point-to-
* point mode, where only TEI 0 is used ("Anlagenanschluss" in German).
* Many thanks to Klaus Heske for his testing efforts.
* - The source number "0" in outgoing calls is now expanded to
* +<country><area>0. This may be useful for point-to-point setups,
* when <area> contains area code and local number without extension.
* - Basic support for different codesets in (E)DSS1 messages. Except
* for codeset 0, unknown information elements are now silently
* ignored (controlled by ignore_unknown_IE in isdnlog/isdnlog.h).
* - Added some information elements to isdnlog/messages.c.
* - Increased the length of msn (local number) in struct telnum.
* - Fixed separation of country and area code for long numbers
* in getDest, tools/dest.c.
* - Changed broken (with gcc 2.95.2) generation of .depend. The old
* output did not consider the location of objectfiles in subdirs.
* Remove this file before compiling this upgraded isdnlog.
* - Moved DUALFIX... defines from tools/tools.h to isdnlog/isdnlog.h.
* - Added missing R:-Links for cellphone entries in country-de.dat.
* - Different entry for each city "Neustadt" in tools/zone/de/code.
* - Earlier changes since isdnlog-4.65:
* - Allow dualmode workaround 0x100 (DUALFIX_DESTNUM) to work also with
* CALL_PROCEEDING messages for cleaning up unanswered incoming calls.
*
* Revision 1.25 2001/06/08 11:55:24 kai
* fix to compile with newer kernel headers. Maybe someone wants to fix isdnlog to recognize the number of channels at run time?
*
* Revision 1.24 1999/12/31 13:30:02 akool
* isdnlog-4.00 (Millenium-Edition)
* - Oracle support added by Jan Bolt (Jan.Bolt@t-online.de)
*
* Revision 1.23 1999/11/16 18:09:39 akool

* there is a patch and a repair program available at
* http://www.toetsch.at/linux/i4l/i4l-3_66.htm
*
* Revision 1.22 1999/09/11 22:28:24 akool

*
* WARNING: This is pre-ALPHA-dont-ever-use-Code!
* "tarif.dat" (aka "rate-xx.dat"): the next generation!
*
* You have to do the following to test this version:
* cp /usr/src/isdn4k-utils/isdnlog/holiday-de.dat /etc/isdn
* cp /usr/src/isdn4k-utils/isdnlog/rate-de.dat /usr/lib/isdn
* cp /usr/src/isdn4k-utils/isdnlog/samples/rate.conf.de /etc/isdn/rate.conf
*
* After that, add the following entries to your "/etc/isdn/isdn.conf" or
* "/etc/isdn/callerid.conf" file:
*
* [ISDNLOG]
* SPECIALNUMBERS = /usr/lib/isdn/sonderrufnummern.dat
* HOLIDAYS = /usr/lib/isdn/holiday-de.dat
* RATEFILE = /usr/lib/isdn/rate-de.dat
* RATECONF = /etc/isdn/rate.conf
*
* Please replace any "de" with your country code ("at", "ch", "nl")
*
* Good luck (Andreas Kool and Michael Reinelt)
