HISAXCTRL(8) Linux System Administration HISAXCTRL(8)NAME
hisaxctrl - configure HiSax-Module
SYNOPSIS
hisaxctrl DriverId command parameters
DESCRIPTION
hisaxctrl is used to setup the HiSax-ISDN device driver. All logging-output is sent to the device /dev/isdnctrl. So you can show it by
executing cat /dev/isdnctrl.
NOTE: for devfs systems, the program will automatically use /dev/isdn/isdnctrl if available.
The use of hisaxctrl only makes sense if you are using the HiSax driver.
OPTIONS
DriverId
is used to identify the card when using more than one passive card. While loading the hisax module with insmod, or modprobe the
DriverId is set by appending id=idstring1%idstring2%... to the commandline.
command
is an integer selecting the setup category. The following values are defined for setting the logging-level of the HiSax-ISDN device
driver:
0 reports card status infos.
1 selects generic debugging.
11 selects layer 1 development debugging.
13 selects layer 3 development debugging.
the following commands are used to enable special features during runtime of the HiSax-ISDN device driver.
2 set B-channel ON delay to parameter (in ms)
5 set B-channel in leased mode
6 set B-channel in TESTLOOP mode
7 set/reset card in Point To Point mode
8 set card in FIXED TEI mode
9 load firmware for DSP cards
10 set B-channel usage limit to 1 or 2 channels
12 set echo logging mode (only for some cards)
B-channel usage limit needs to be 1 if enabled
parameter
If the command is 9 then the parameter is the full pathname to the file containing the firmware.
For debug settings this is an integer representing a bitmask. Every bit in this mask switches a debug facility on or off. Depending
on the selected category, the following values are defined:
With generic debugging selected
(command 1):
0x001 Link-level <--> hardware-level communication
0x002 Top state machine
0x004 D-Channel Q.931 (call control messages)
0x008 D-Channel Q.921
0x010 B-Channel X.75
0x020 D-Channel l2
0x040 B-Channel l2
0x080 D-Channel link state debugging
0x100 B-Channel link state debugging
0x200 TEI debug
0x400 LOCK debug in callc.c
0x800 More debug in callc.c (not for normal use)
With layer 1 development debugging selected
(command 11):
0x001 Warnings (default: on)
0x002 IRQ status
0x004 ISAC
0x008 ISAC FIFO
0x010 HSCX
0x020 HSCX FIFO (attention: full B-Channel output!)
0x040 D-Channel LAPD frame types
With layer 3 development debugging selected
(command 13):
0x001 Warnings (default: on)
0x002 l3 protocol discriptor errors
0x004 l3 state machine
0x008 charge info debugging (1TR6)
EXAMPLE
hisaxctrl HiSax 1 0x3ff
enables full generic debugging.

isdninfo - ISDN status device
SYNOPSIS
#include <linux/isdn.h>
DESCRIPTION
/dev/isdninfo is a character device with major number 45 and minor number 255. It delivers status information from the Linux ISDN subsys-
tem to user level.
DATA FORMAT
When reading from this device, the current status of the Linux ISDN subsystem is delivered in 6 lines of text. Each line starts with a tag
string followed by a colon and whitespace. After that the status values are appended separated by whitespace.
idmap is the tag of the first line. In this line for every virtual channel, the Id-string of the corresponding lowlevel driver is shown.
If no driver is loaded, a - (hyphen) is shown.
chmap is the tag of line 2. In this line for every virtual channel, the channel number of the corresponding lowlevel driver is shown. If
no driver is loaded, -1 is shown.
drmap is the tag of line 3. In this line for every virtual channel, the index number of the corresponding lowlevel driver is shown. If no
driver is loaded, -1 is shown.
usage is the tag of line 4. In this line for every virtual channel, the current usage is shown. The following usage constants are defined:
ISDN_USAGE_NONE (0)
Unused channel
ISDN_USAGE_RAW (1)
Channel used by raw device (currently unsupported)
ISDN_USAGE_MODEM (2)
Channel used by some ttyI
ISDN_USAGE_NET (3)
Channel used by an ISDN net-interface
ISDN_USAGE_VOICE (4)
Channel used by some ttyI in voice mode.
ISDN_USAGE_EXCLUSIVE (64)
Channel exclusively preserved for a net-interface. This value is logically or'ed with one of the other codes.
ISDN_USAGE_OUTGOING (128)
Channel is used outgoing. This value is logically or'ed with one of the other codes. It is set, when dialling is started and
reset, when either dialling failed or after hangup. Therefore, it is not always an indicator for an established connection.
To get a reliable indicator for an established connection, the driver flags (see below) have to be inspected also.
flags is the tag of line 5. In this line for every driver slot, it's B-Channel status is shown. If no driver is registered in a slot, a ?
is shown. For every established B-Channel of the driver, a bit is set in the shown value. The driver's first channel is mapped to
bit 0, the second channel to bit 1 and so on.
phone is the tag of line 6. In this line for every virtual channel, the remote phone number is shown if the channel is active. A ??? is
shown, if the channel is inactive.
BLOCKING BEHAVIOUR
After opening the device, at most 6 lines can be read by a user process. After that, the user process is blocked. Whenever a status change
happens, the process is allowed to read 6 more lines, starting with line one.
IOCTL FUNCTIONS
Currently, there are two ioctl calls supported:
IIOCGETDVR
Get Revision information.
Returns an unsigned long value v, representing various user level interface revisions, where
(v & 0xff)
is the revision of the modem-register info, available via ioctl on /dev/isdnctrl.
((v >> 8) & 0xff)
is the revision of the net-interface config data, available via ioctl on /dev/isdnctrl. and
((v >> 16) & 0xff)
is the revision of the data delivered via /dev/isdninfo itself.
IIOCGETCPS
Get transfer statistics.
Returns the number of bytes transferred so far for all virtual channels. The third parameter should be a pointer to an array of
unsigned long of size ISDN_MAX_CHANNELS * 2. This array is filled with the byte counter values upon return.
OTHER CONSTANTS
There are some more useful constants defined in /usr/include/linux/isdn.h:
ISDN_TTY_MAJOR
The major device number of /dev/ttyI.
ISDN_TTYAUX_MAJOR
The major device number of /dev/cui.
ISDN_MAJOR
The major device number of /dev/isdnctrl, /dev/isdninfo, /dev/ippp and /dev/isdn
ISDN_MAX_DRIVERS
The number of driver slots.
ISDN_MAX_CHANNELS
The number of virtual channels.
ISDN_MINOR_CTRL
The minor device number of /dev/isdnctrl0.
ISDN_MINOR_CTRLMAX
The minor device number of /dev/isdnctrl63.
ISDN_MINOR_PPP
The minor device number of /dev/ippp0.
ISDN_MINOR_PPPMAX
The minor device number of /dev/ippp64.
ISDN_MINOR_STATUS
The minor device number of /dev/isdninfo.
Other constants, necessary for ioctl's on /dev/isdnctrl are listed in isdnctrl(4).
