NAME

       icnctrl - configure ICN ISDN adaptor

SYNOPSIS

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

DESCRIPTION

       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.

OPTIONS

       -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  misinter-
	      preted 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  spe-
	      cial "phone-numbers" for calling and called address which are generated as follows:

	      Calling number:
		     LEASEDx
			    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:
		     x
			    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 dif-
	      ferent 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.

FILES

       @DATADIR@/loadpg.bin
	      This is the image of the bootstrap loader, which is loaded first, then loads the firmware into the card's memory and  starts  execu-
	      tion.

       @DATADIR@/pc_1t_ca.bin
	      This is the image of the firmware designed for the German 1TR6 protocol.

       @DATADIR@/pc_eu_ca.bin
	      This is the image of the firmware, designed for Euro ISDN.

DIAGNOSTICS

       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.

BUGS

       No bugs so far.
