ICNCTRL(8) Linux System Administration ICNCTRL(8)
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 download-
ing 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 descrip-
tion 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 sin-
gle 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 download-
ing 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:
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 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 sup-
plied. 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 execution.
@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.
