       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  initialisa­
              tion. See icn(4) for a description of the syntax to
              be used for modularised and monolithic driver  ver­
              sions.  This option must be used to identify the S0
              interface if more than one S0  interface  is  exis­
              tent.  If  a single ICN-2B is used, it may be omit­
              ted.  If using more than one card, support for  the
              other cards is enabled with the add action of icnc­
              trl. 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-con­
              flicts. Ports are checked later during first  acti­
              vation  while  downloading  the firmware and can be
              changed at runtime. Ids are  checked  against  con­
              flicts,  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

       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 dif­
              ferent from the default settings  below.   If  both
              parameters  are  omitted,  prints  out current set­
              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 num­
                             ber  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 set­
              tings 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.
