 * 
 * Copyright 1996 by Carsten Paeth (calle@calle.in-berlin.de)
 * 
 * $Log: avmcapictrl.c,v $
 * Revision 1.16  2001/03/01 14:59:11  paul
 * Various patches to fix errors when using the newest glibc,
 * replaced use of insecure tempnam() function
 * and to remove warnings etc.
 *
 * Revision 1.15  2000/03/08 13:40:33  calle
 * check for /dev/isdn/capi20 if /dev/capi20 doesn't exist.
 *
 * Revision 1.14  2000/01/28 16:36:19  calle
 * generic addcard (call add_card function of named driver)
 *
 * Revision 1.13  1999/12/06 17:01:51  calle
 * more documentation and possible errors explained.
 *
 * Revision 1.12  1999/07/01 16:37:53  calle
 * New command with new driver
 *    avmcapictrl trace [contrnr] [off|short|on|full|shortnodate|nodata]
 * to make traces of capi messages per controller.
 *
 * Revision 1.11  1999/06/21 15:30:45  calle
 * extend error message if io port is out of range, now tell user that an
 * AVM B1 PCI card must be added by loading module b1pci.
 *
 * Revision 1.10  1998/07/15 15:08:20  calle
 * port and irq check changed.
 *
 * Revision 1.9  1998/02/27 15:42:00  calle
 * T1 running with slow link.
 *
 * Revision 1.8  1998/02/24 17:56:23  calle
 * changes for T1.
 *
 * Revision 1.7  1998/02/07 20:32:00  calle
 * update man page, remove old cardtype M1, add is done via avm_cs.o
 *
 * Revision 1.6  1998/02/07 20:09:00  calle
 * - added support for DN1/SPID1 DN2/SPID2 for 5ESS und NI1 protocols.
 * - allow debuging of patchvalues.
 * - optimize configure.in/configure
 *
 * Revision 1.5  1998/01/16 14:02:08  calle
 * patchvalues working now, leased lines and dchannel protocols like
 * CT1,VN3 und AUSTEL support okay, point to point also patchable.
 *
 * Revision 1.3  1997/12/07 20:02:22  calle
 * prepared support for cardtype and different protocols
 *
 * Revision 1.2  1997/03/20 00:18:57  luethje
 * inserted the line #include <errno.h> in avmb1/avmcapictrl.c and imon/imon.c,
 * some bugfixes, new structure in isdnlog/isdnrep/isdnrep.c.
 *
 * Revision 1.1  1997/03/04 22:46:32  calle
 * Added program to add and download firmware to AVM-B1 card
 *
 * Revision 2.2  1997/02/12 09:31:39  calle
 * more verbose error messages
 *
 * Revision 1.1  1997/01/31 10:32:20  calle
 * Initial revision
