       icnctrl - configure ICN ISDN adaptor


       icnctrl [-d Driver-Id] action options ...


       icnctrl is used to setup the ICN ISDN device driver and for downloading
       the firmware into the ISDN card.

       The use of icnctrl makes sense, if you are using an ICN card only.


       -d Driver-Id
              selects the S0 interface named  by  Driver-Id.   Driver-Ids  are
              defined   during   driver   initialisation.  See  icn(4)  for  a
              description of  the  syntax  to  be  used  for  modularised  and
              monolithic  driver  versions.   This  option  must  be  used  to
              identify the S0 interface if  more  than  one  S0  interface  is
              existent.  If  a  single  ICN-2B is used, it may be omitted.  If
              using more than one card, support for the other cards is enabled
              with the add action of icnctrl. Ids may not start with digits or
              small x, because these  values  are  misinterpreted  as  numeric
              parameters by insmod.  For loading the module, always the newest
              modutils package should be used to avoid problems during load.

       The following actions may be given to icnctrl.

       add port [id1 [id2]]
              enables support for an additional card in the driver. If id1 and
              id2  are missing, adds an ICN-2B with an id given by the system.
              with id2 missing, adds an ICN-2B with an Id given by  the  user.
              With  both  Ids given, adds an ICN-4B with both Ids given by the
              user. There is no checking  against  port-conflicts.  Ports  are
              checked  later  during  first  activation  while downloading the
              firmware and can be changed at runtime. Ids are checked  against
              conflicts,  and if a conflict happens, replaced by the system in
              the same manner as if no Id was supplied. It is not allowed,  to
              add cards, after a load was done.

       io [base-address port]
              sets  the  address  of the memory-mapped IO-region and the port-
              base.  After loading  the  icn-module  into  kernel-space,  this
              command  should be used as the very first setup, if the hardware
              settings are different from the default settings below.  If both
              parameters are omitted, prints out current settings. The default
              memory address is 0xD0000, the default port-base is  0x320.   An
              ICN  card  uses 4 port-addresses. The memory address is globally
              used for all cards (cards are mapped on demand), while each card
              has its own port range. Memory range is 16k.

       leased on|1|2|off
              switches  between  normal (dialup) and leased-line mode. Leased-
              line mode is intended for usage with S64K-lines  or  -  if  both
              channels are used - for S02. If the second parameter is 1 , only
              one channel is enabled.  If the second parameter is 2 or on both
              channels are enabled. Leased lines do not have a D-channel. When
              leased-line mode is enabled, the driver simulates incoming calls
              using  special  "phone-numbers"  for  calling and called address
              which are generated as follows:

              Calling number:
                             where x is the internal  slot-number  of  the  S0
                             interface.  This  number  starts  with  0 for the
                             first S0 interface and is incremented by one  for
                             every  S0  interface  configured  using  the  add

              Called number:
                             where x is equal to the  channel  number  of  the
                             calling S0 interface starting with 1.

       load boot-code firmware [firmware2]
              downloads the firmware into the card and starts operation. Using
              this command, after loading the icn-module into kernel-space the
              first  real  access  to  the  hardware is done. Therefore the io
              action above, should be used before, if  the  hardware  settings
              are different from the default settings.  Usually the images are
              located in @DATADIR@.  The boot-code is named  loadpg.bin.   The
              firmware depends on the D-channel protocol of the ISDN line. For
              German 1TR6-lines, the  firmware  is  named  pc_1t_ca.bin.   For
              Euro-ISDN-lines,  it  is  named  pc_eu_ca.bin.   When loading an
              ICN-4B, two firmware parameters have to be supplied.  The  first
              firmware is used for the upper S0 connector, the second firmware
              is used for the lower S0  connector  (towards  the  card’s  slot

       dump   is  available  if  the program is configured using the --enable-
              dump option only. The contents of internal driver  variables  is
              dumped on stdout.


              This  is  the  image  of  the  bootstrap loader, which is loaded
              first, then loads the firmware into the card’s memory and starts

              This  is  the image of the firmware designed for the German 1TR6

              This is the image of the firmware, designed for Euro ISDN.


       The following diagnostics may be issued on stderr:

       Read error on boot-code
              The file supplied as boot-code has less than 4096  bytes  length
              or could not be read.

       Read error on firmware
              The  file  supplied as firmware has less than 65536 bytes length
              or could not be read.


       No bugs so far.
