       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 action.

              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 connector).

       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 execution.

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

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


       No bugs so far.
