“cat /proc/pci” as “tiger” or similar.
To use ISDN types 104 to 114 the matching drivers have to be downloaded from http:
//www.fli4l.de/download/stabile-version/avm-treiber/. Unpack them to the fli4l di-
rectory. They cannot be included because these drivers are not gpl’d.
For ISDN types 81, 82, 109 to 113 and 303 it is necessary to activate USB support. See
USB - Support for USB-devices (Page 231).
To use ISDN types 10, 22, 26, 39, 103 or 114 it is necessary to activate PCMCIA PC-Card
support. See PCMCIA - PC-Card Support (Page 185).
If you really don’t know what card is in your PC you can get tips for type numbers also
from the i4l-FAQ or mailing list.
Card types that are signed „from isapnp setup“ have to be initialized by the PnP tool
isapnp - if they really are PnP cards. See OPT_PNP - Installation of isapnp tools
(Page 76).
ISDN type 0 is used if the ISDN package should be installed without an ISDN card, for
example to use imond in a network router.
ISDN_DEBUG_LEVEL Sets the debug level for the HiSaX driver. Debug level is concate-
nated by addition of the following values (cited from the orginal docs):
Number Debug-Information
1 Link-level – hardware-level communication
2 Top state machine
4 D-Channel Q.931 (call control messages)
8 D-Channel Q.921
16 B-Channel X.75
32 D-Channel l2
64 B-Channel l2
128 D-Channel link state debugging
256 B-Channel link state debugging
512 TEI debug
1024 LOCK debug in callc.c
2048 More debug in callc.c (not for normal use)
The default setting (ISDN_DEBUG_LEVEL=’31’) should be enough for most purposes.
ISDN_VERBOSE_LEVEL Sets the “verbosity” of the ISDN subsystem in fli4l kernel. Each
verbose-level includes levels with lower numbers. Verbose levels are:
’0’ no additional informations
’1’ events triggering an ISDN connection will be logged
’2’ and ’3’ Calls are logged
’4’ and more Data transfer rates will be logged
Messages are sent over the kernel logging interface activated by OPT_SYSLOGD (Page 73).
