Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2 
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

Raw Blame History

HiSax is a Linux hardware-level driver for passive ISDN cards with Siemens
chipset (ISAC_S 2085/2086/2186, HSCX SAB 82525). It is based on the Teles
driver from Jan den Ouden.
It is meant to be used with isdn4linux, an ISDN link-level module for Linux
written by Fritz Elfert.

If you know other passive cards with the Siemens chipset, please let me know.
You can combine any card, if there is no conflict between the resources
(io, mem, irq).
Configuring the driver
----------------------
The HiSax driver can either be built directly into the kernel or as a module.
It can be configured using the command line feature while loading the kernel
with LILO or LOADLIN or, if built as a module, using insmod/modprobe with
parameters.
There is also some config needed before you compile the kernel and/or
modules. It is included in the normal "make [menu]config" target at the
kernel. Don't forget it, especially to select the right D-channel protocol.
Please note: In older versions of the HiSax driver, all PnP cards
needed to be configured with isapnp and worked only with the HiSax
driver used as a module.
In the current version, HiSax will automatically use the in-kernel
ISAPnP support, provided you selected it during kernel configuration
(CONFIG_ISAPNP), if you don't give the io=, irq= command line parameters.
The affected card types are: 4,7,12,14,19,27-30
a) when built as a module
-------------------------
insmod/modprobe hisax.o \
io=iobase irq=IRQ mem=membase type=card_type \
protocol=D_channel_protocol id=idstring
or, if several cards are installed:
insmod/modprobe hisax.o \
io=iobase1,iobase2,... irq=IRQ1,IRQ2,... mem=membase1,membase2,... \
type=card_type1,card_type2,... \
protocol=D_channel_protocol1,D_channel_protocol2,... \
id=idstring1%idstring2 ...
where "iobaseN" represents the I/O base address of the Nth card, "membaseN"
the memory base address of the Nth card, etc.
The reason for the delimiter "%" being used in the idstrings is that ","
won't work with the current modules package.
The parameters may be specified in any order. For example, the "io"
parameter may precede the "irq" parameter, or vice versa. If several
cards are installed, the ordering within the comma separated parameter
lists must of course be consistent.
Only parameters applicable to the card type need to be specified. For
example, the Teles 16.3 card is not memory-mapped, so the "mem"
parameter may be omitted for this card. Sometimes it may be necessary
to specify a dummy parameter, however. This is the case when there is
a card of a different type later in the list that needs a parameter
which the preceding card does not. For instance, if a Teles 16.0 card
is listed after a Teles 16.3 card, a dummy memory base parameter of 0
must be specified for the 16.3. Instead of a dummy value, the parameter
can also be skipped by simply omitting the value. For example:
mem=,0xd0000. See example 6 below.
The parameter for the D-Channel protocol may be omitted if you selected the
correct one during kernel config. Valid values are "1" for German 1TR6,
"2" for EDSS1 (Euro ISDN), "3" for leased lines (no D-Channel) and "4"
for US NI1.
With US NI1 you have to include your SPID into the MSN setting in the form
<MSN>:<SPID> for example (your phonenumber is 1234 your SPID 5678):
AT&E1234:5678 on ttyI interfaces
isdnctrl eaz ippp0 1234:5678 on network devices
The Creatix/Teles PnP cards use io1= and io2= instead of io= for specifying
the I/O addresses of the ISAC and HSCX chips, respectively.
Card types:
Type Required parameters (in addition to type and protocol)
1 Teles 16.0 irq, mem, io
2 Teles 8.0 irq, mem

At the moment IRQ sharing is only possible with PCI cards. Please make sure
that your IRQ is free and enabled for ISA use.
Examples for module loading
1. Teles 16.3, Euro ISDN, I/O base 280 hex, IRQ 10
modprobe hisax type=3 protocol=2 io=0x280 irq=10
2. Teles 16.0, 1TR6 ISDN, I/O base d80 hex, IRQ 5, Memory d0000 hex
modprobe hisax protocol=1 type=1 io=0xd80 mem=0xd0000 irq=5
3. Fritzcard, Euro ISDN, I/O base 340 hex, IRQ 10 and ELSA PCF, Euro ISDN
modprobe hisax type=5,6 protocol=2,2 io=0x340 irq=10 id=Fritz%Elsa
4. Any ELSA PCC/PCF card, Euro ISDN
modprobe hisax type=6 protocol=2
5. Teles 16.3 PnP, Euro ISDN, with isapnp configured
isapnp config: (INT 0 (IRQ 10 (MODE +E)))
(IO 0 (BASE 0x0580))
(IO 1 (BASE 0x0180))
modprobe hisax type=4 protocol=2 irq=10 io0=0x580 io1=0x180
In the current version of HiSax, you can instead simply use
modprobe hisax type=4 protocol=2
if you configured your kernel for ISAPnP. Don't run isapnp in
this case!
6. Teles 16.3, Euro ISDN, I/O base 280 hex, IRQ 12 and
Teles 16.0, 1TR6, IRQ 5, Memory d0000 hex
modprobe hisax type=3,1 protocol=2,1 io=0x280 mem=0,0xd0000
Please note the dummy 0 memory address for the Teles 16.3, used as a
placeholder as described above, in the last example.
7. Teles PCMCIA, Euro ISDN, I/O base 180 hex, IRQ 15 (default values)
modprobe hisax type=8 protocol=2 io=0x180 irq=15

where
typ1 = type of 1st card (default depends on kernel settings)
dp1 = D-Channel protocol of 1st card. 1=1TR6, 2=EDSS1, 3=leased
pa_1 = 1st parameter (depending on the type of the card)
pb_1 = 2nd parameter ( " " " " " " " )
pc_1 = 3rd parameter ( " " " " " " " )
typ2,dp2,pa_2,pb_2,pc_2 = Parameters of the second card (defaults: none)
typn,dpn,pa_n,pb_n,pc_n = Parameters of the n'th card (up to 16 cards are
supported)
idstring = Driver ID for accessing the particular card with utility
programs and for identification when using a line monitor
(default: "HiSax")
Note: the ID string must start with an alphabetical character!

Running the driver
------------------
When you insmod isdn.o and hisax.o (or with the in-kernel version, during
boot time), a few lines should appear in your syslog. Look for something like:
Apr 13 21:01:59 kke01 kernel: HiSax: Driver for Siemens chip set ISDN cards
Apr 13 21:01:59 kke01 kernel: HiSax: Version 2.9
Apr 13 21:01:59 kke01 kernel: HiSax: Revisions 1.14/1.9/1.10/1.25/1.8
Apr 13 21:01:59 kke01 kernel: HiSax: Total 1 card defined
Apr 13 21:01:59 kke01 kernel: HiSax: Card 1 Protocol EDSS1 Id=HiSax1 (0)
Apr 13 21:01:59 kke01 kernel: HiSax: Elsa driver Rev. 1.13
...
Apr 13 21:01:59 kke01 kernel: Elsa: PCF-Pro found at 0x360 Rev.:C IRQ 10
Apr 13 21:01:59 kke01 kernel: Elsa: timer OK; resetting card
Apr 13 21:01:59 kke01 kernel: Elsa: HSCX version A: V2.1 B: V2.1
Apr 13 21:01:59 kke01 kernel: Elsa: ISAC 2086/2186 V1.1
...
Apr 13 21:01:59 kke01 kernel: HiSax: DSS1 Rev. 1.14
Apr 13 21:01:59 kke01 kernel: HiSax: 2 channels added
This means that the card is ready for use.
Cabling problems or line-downs are not detected, and only some ELSA cards can
detect the S0 power.
Remember that, according to the new strategy for accessing low-level drivers
from within isdn4linux, you should also define a driver ID while doing
insmod: Simply append hisax_id=<SomeString> to the insmod command line. This
string MUST NOT start with a digit or a small 'x'!
At this point you can run a 'cat /dev/isdnctrl0' and view debugging messages.
At the moment, debugging messages are enabled with the hisaxctrl tool:
hisaxctrl <DriverId> DebugCmd <debugging_flags>
<DriverId> default is HiSax, if you didn't specify one.
DebugCmd is 1 for generic debugging
11 for layer 1 development debugging
13 for layer 3 development debugging
where <debugging_flags> is the integer sum of the following debugging
options you wish enabled:
With DebugCmd set to 1:
0x0001 Link-level <--> hardware-level communication
0x0002 Top state machine
0x0004 D-Channel Frames for isdnlog
0x0008 D-Channel Q.921
0x0010 B-Channel X.75
0x0020 D-Channel l2
0x0040 B-Channel l2
0x0080 D-Channel link state debugging
0x0100 B-Channel link state debugging
0x0200 TEI debug
0x0400 LOCK debug in callc.c
0x0800 More paranoid debug in callc.c (not for normal use)
0x1000 D-Channel l1 state debugging
0x2000 B-Channel l1 state debugging
With DebugCmd set to 11:
0x0001 Warnings (default: on)
0x0002 IRQ status
0x0004 ISAC
0x0008 ISAC FIFO
0x0010 HSCX
0x0020 HSCX FIFO (attention: full B-Channel output!)
0x0040 D-Channel LAPD frame types
0x0080 IPAC debug
0x0100 HFC receive debug
0x0200 ISAC monitor debug
0x0400 D-Channel frames for isdnlog (set with 1 0x4 too)
0x0800 D-Channel message verbose
With DebugCmd set to 13:
1 Warnings (default: on)
2 l3 protocol descriptor errors
4 l3 state machine
8 charge info debugging (1TR6)
For example, 'hisaxctrl HiSax 1 0x3ff' enables full generic debugging.
Because of some obscure problems with some switch equipment, the delay
between the CONNECT message and sending the first data on the B-channel is now
configurable with
hisaxctrl <DriverId> 2 <delay>
<delay> in ms Value between 50 and 800 ms is recommended.
Downloading Firmware
--------------------
At the moment, the Sedlbauer speed fax+ is the only card, which
needs to download firmware.
The firmware is downloaded with the hisaxctrl tool:
hisaxctrl <DriverId> 9 <firmware_filename>
<DriverId> default is HiSax, if you didn't specify one,
where <firmware_filename> is the filename of the firmware file.
For example, 'hisaxctrl HiSax 9 ISAR.BIN' downloads the firmware for
ISAR based cards (like the Sedlbauer speed fax+).
Warning
-------
HiSax is a work in progress and may crash your machine.
For certification look at HiSax.cert file.
Limitations
-----------
At this time, HiSax only works on Euro ISDN lines and German 1TR6 lines.
For leased lines see appendix.
Bugs
----
If you find any, please let me know.

for instructions.
Appendix: Linux and ISDN-leased lines
-------------------------------------
Original from Juergen Quade, new version KKe.
Attention NEW VERSION, the old leased line syntax won't work !!!
You can use HiSax to connect your Linux-Box via an ISDN leased line
to e.g. the Internet:
1. Build a kernel which includes the HiSax driver either as a module
or as part of the kernel.
cd /usr/src/linux
make menuconfig
<ISDN subsystem - ISDN support -- HiSax>
make clean; make zImage; make modules; make modules_install
2. Install the new kernel
cp /usr/src/linux/arch/i386/boot/zImage /etc/kernel/linux.isdn
vi /etc/lilo.conf
<add new kernel in the bootable image section>
lilo
3. in case the hisax driver is a "fixed" part of the kernel, configure
the driver with lilo:
vi /etc/lilo.conf
<add HiSax driver parameter in the global section (see below)>
lilo
Your lilo.conf _might_ look like the following:
# LILO configuration-file
# global section
# teles 16.0 on IRQ=5, MEM=0xd8000, PORT=0xd80
append="hisax=1,3,5,0xd8000,0xd80,HiSax"
# teles 16.3 (non pnp) on IRQ=15, PORT=0xd80
# append="hisax=3,3,5,0xd8000,0xd80,HiSax"
boot=/dev/sda
compact # faster, but won't work on all systems.
linear
read-only
prompt
timeout=100
vga = normal # force sane state
# Linux bootable partition config begins
image = /etc/kernel/linux.isdn
root = /dev/sda1
label = linux.isdn
#
image = /etc/kernel/linux-2.0.30
root = /dev/sda1
label = linux.secure
In the line starting with "append" you have to adapt the parameters
according to your card (see above in this file)
3. boot the new linux.isdn kernel
4. start the ISDN subsystem:
a) load - if necessary - the modules (depends, whether you compiled
the ISDN driver as module or not)
According to the type of card you have to specify the necessary
driver parameter (irq, io, mem, type, protocol).
For the leased line the protocol is "3". See the table above for
the parameters, which you have to specify depending on your card.
b) configure i4l
/sbin/isdnctrl addif isdn0
# EAZ 1 -- B1 channel 2 --B2 channel
/sbin/isdnctrl eaz isdn0 1
/sbin/isdnctrl secure isdn0 on
/sbin/isdnctrl huptimeout isdn0 0
/sbin/isdnctrl l2_prot isdn0 hdlc
# Attention you must not set an outgoing number !!! This won't work !!!
# The incoming number is LEASED0 for the first card, LEASED1 for the
# second and so on.
/sbin/isdnctrl addphone isdn0 in LEASED0
# Here is no need to bind the channel.
c) in case the remote partner is a CISCO:
/sbin/isdnctrl encap isdn0 cisco-h
d) configure the interface
/sbin/ifconfig isdn0 ${LOCAL_IP} pointopoint ${REMOTE_IP}
e) set the routes
/sbin/route add -host ${REMOTE_IP} isdn0
/sbin/route add default gw ${REMOTE_IP}
f) switch the card into leased mode for each used B-channel
/sbin/hisaxctrl HiSax 5 1
Remarks:
a) Use state of the art isdn4k-utils
Here an example script:
#!/bin/sh
# Start/Stop ISDN leased line connection
