-Welcome to Beta Release 2 of the combination ISDN driver for SpellCaster's
-ISA ISDN adapters. Please note this release 2 includes support for the
-DataCommute/BRI and TeleCommute/BRI adapters only and any other use is
-guaranteed to fail. If you have a DataCommute/PRI installed in the test
-computer, we recommend removing it as it will be detected but will not
-be usable. To see what we have done to Beta Release 2, see section 3.

-1. Introduction
----------------
-
-The revision 2 Linux driver for SpellCaster ISA ISDN adapters is built
-upon ISDN4Linux available separately or as included in Linux 2.0 and later.
-The driver will support a maximum of 4 adapters in any one system of any
-type including DataCommute/BRI, DataCommute/PRI and TeleCommute/BRI for a
-maximum of 92 channels for host. The driver is supplied as a module in
-source form and needs to be complied before it can be used. It has been
-tested on Linux 2.0.20.
-
-1.1 What Is ISDN4Linux
-
-ISDN4Linux is a driver and set of tools used to access and use ISDN devices
-on a Linux platform in a common and standard way. It supports HDLC and PPP
-protocols and offers channel bundling and MLPPP support. To use ISDN4Linux
-you need to configure your kernel for ISDN support and get the ISDN4Linux
-tool kit from our web site.
-
-ISDN4Linux creates a channel pool from all of the available ISDN channels
-and therefore can function across adapters. When an ISDN4Linux compliant
-driver (such as ours) is loaded, all of the channels go into a pool and
-are used on a first-come first-served basis. In addition, individual
-channels can be specifically bound to particular interfaces.
-
-1.2 What is different between this driver and previous drivers?
-
-The revision 2 driver besides adopting the ISDN4Linux architecture has many
-subtle and not so subtle functional differences from previous releases. These
-include:
- - More efficient shared memory management combined with a simpler
- configuration. All adapters now use only 16Kbytes of shared RAM
- versus between 16K and 64K. New methods for using the shared RAM
- allow us to utilize all of the available RAM on the adapter through
- only one 16K page.
- - Better detection of available upper memory. The probing routines
- have been improved to better detect available shared RAM pages and
- used pages are now locked.
- - Decreased loading time and a wider range of I/O ports probed.
- We have significantly reduced the amount of time it takes to load
- the driver and at the same time doubled the number of I/O ports
- probed increasing the likelihood of finding an adapter.
- - We now support all ISA adapter models with a single driver instead
- of separate drivers for each model. The revision 2 driver supports
- the DataCommute/BRI, DataCommute/PRI and TeleCommute/BRI in any
- combination up to a maximum of four adapters per system.
- - On board PPP protocol support has been removed in favour of the
- sync-PPP support used in ISDN4Linux. This means more control of
- the protocol parameters, faster negotiation time and a more
- familiar interface.
-
-1.3 How do I setup my system with the correct software to use
- this driver release?
-
-Before you can compile, install and use the SpellCaster ISA ISDN driver, you
-must ensure that the following software is installed, configured and running:
-
- - Linux kernel 2.0.20 or later with the required init and ps
- versions. Please see your distribution vendor for the correct
- utility packages. The latest kernel is available from
- ftp://sunsite.unc.edu/pub/Linux/kernel/v2.0/
-
- - The latest modules package (modules-2.0.0.tar.gz) from
- ftp://sunsite.unc.edu/pub/Linux/kernel/modules-2.0.0.tar.gz
-
- - The ISDN4Linux tools available from
- ftp://ftp.franken.de/pub/isdn4linux/v2.0/isdn4k-utils-2.0.tar.gz
- This package may fail to compile for you so you can alternatively
- get a pre-compiled version from
- ftp://ftp.spellcast.com/pub/drivers/isdn4linux/isdn4k-bin-2.0.tar.gz
-
-
-2. Basic Operations
--------------------
-
-2.1 Unpacking and installing the driver
-
- 1. As root, create a directory in a convenient place. We suggest
- /usr/src/spellcaster.
-
- 2. Unpack the archive with :
- tar xzf sc-n.nn.tar.gz -C /usr/src/spellcaster
-
- 3. Change directory to /usr/src/spellcaster
-
- 4. Read the README and RELNOTES files.
-
- 5. Run 'make' and if all goes well, run 'make install'.
-
-2.2 Read the man pages!!!
-
-Make sure you read the scctrl(8) and sc(4) manual pages before continuing
-any further. Type 'man 8 scctrl' and 'man 4 sc'.
-
-2.3 Installing the driver
-
-To install the driver, type '/sbin/insmod sc' as root. sc(4) details options
-you can specify but you shouldn't need to use any unless this doesn't work.
-
-Make sure the driver loaded and detected all of the adapters by typing
-'dmesg'.
-
-The driver can be configured so that it is loaded upon startup. To do this,
-edit the file "/etc/modules/'uname -f'/'uname -v'" and insert the driver name
-"sc" into this file.
-
-2.4 Removing the driver
-
-To remove the driver, delete any interfaces that may exist (see isdnctrl(8)
-for more on this) and then type '/sbin/rmmod sc'.
-
-2.5 What to do if it doesn't load
-
-If, when you try to install the driver, you get a message mentioning
-'register_isdn' then you do not have the ISDN4Linux system installed. Please
-make sure that ISDN support is configured in the kernel.
-
-If you get a message that says 'initialization of sc failed', then the
-driver failed to detect an adapter or failed to find resources needed such
-as a free IRQ line or shared memory segment. If you are sure there are free
-resources available, use the insmod options detailed in sc(4) to override
-the probing function.
-
-Upon testing, the following problem was noted, the driver would load without
-problems, but the board would not respond beyond that point. When a check was
-done with 'cat /proc/interrupts' the interrupt count for sc was 0. In the event
-of this problem, change the BIOS settings so that the interrupts in question are
-reserved for ISA use only.
-
-
-2.6 How to setup ISDN4Linux with the driver
-
-There are three main configurations which you can use with the driver:
-
-A) Basic HDLC connection
-B) PPP connection
-C) MLPPP connection
-
-It should be mentioned here that you may also use a tty connection if you
-desire. The Documentation directory of the isdn4linux subsystem offers good
-documentation on this feature.
-
-A) 10 steps to the establishment of a basic HDLC connection
------------------------------------------------------------
-
-- please open the isdn-hdlc file in the examples directory and follow along...
-
- This file is a script used to configure a BRI ISDN TA to establish a
- basic HDLC connection between its two channels. Two network
- interfaces are created and two routes added between the channels.
-
- i) using the isdnctrl utility, add an interface with "addif" and
- name it "isdn0"
- ii) add the outgoing and inbound telephone numbers
- iii) set the Layer 2 protocol to hdlc
- iv) set the eaz of the interface to be the phone number of that
- specific channel
- v) to turn the callback features off, set the callback to "off" and
- the callback delay (cbdelay) to 0.
- vi) the hangup timeout can be set to a specified number of seconds
- vii) the hangup upon incoming call can be set on or off
- viii) use the ifconfig command to bring up the network interface with
- a specific IP address and point to point address
- ix) add a route to the IP address through the isdn0 interface
- x) a ping should result in the establishment of the connection
-
-
-B) Establishment of a PPP connection
-------------------------------------
-
-- please open the isdn-ppp file in the examples directory and follow along...
-
- This file is a script used to configure a BRI ISDN TA to establish a
- PPP connection between the two channels. The file is almost
- identical to the HDLC connection example except that the packet
- encapsulation type has to be set.
-
- use the same procedure as in the HDLC connection from steps i) to
- iii) then, after the Layer 2 protocol is set, set the encapsulation
- "encap" to syncppp. With this done, the rest of the steps, iv) to x)
- can be followed from above.
-
- Then, the ipppd (ippp daemon) must be setup:
-
- xi) use the ipppd function found in /sbin/ipppd to set the following:
- xii) take out (minus) VJ compression and bsd compression
- xiii) set the mru size to 2000
- xiv) link the two /dev interfaces to the daemon
-
-NOTE: A "*" in the inbound telephone number specifies that a call can be
-accepted on any number.
-
-C) Establishment of a MLPPP connection
---------------------------------------
-
-- please open the isdn-mppp file in the examples directory and follow along...
-
- This file is a script used to configure a BRI ISDN TA to accept a
- Multi Link PPP connection.
-
- i) using the isdnctrl utility, add an interface with "addif" and
- name it "ippp0"
- ii) add the inbound telephone number
- iii) set the Layer 2 protocol to hdlc and the Layer 3 protocol to
- trans (transparent)
- iv) set the packet encapsulation to syncppp
- v) set the eaz of the interface to be the phone number of that
- specific channel
- vi) to turn the callback features off, set the callback to "off" and
- the callback delay (cbdelay) to 0.
- vi) the hangup timeout can be set to a specified number of seconds
- vii) the hangup upon incoming call can be set on or off
- viii) add a slave interface and name it "ippp32" for example
- ix) set the similar parameters for the ippp32 interface
- x) use the ifconfig command to bring-up the ippp0 interface with a
- specific IP address and point to point address
- xi) add a route to the IP address through the ippp0 interface
- xii) use the ipppd function found in /sbin/ipppd to set the following:
- xiii) take out (minus) bsd compression
- xiv) set the mru size to 2000
- xv) add (+) the multi-link function "+mp"
- xvi) link the two /dev interfaces to the daemon
-
-NOTE: To use the MLPPP connection to dial OUT to a MLPPP connection, change
-the inbound telephone numbers to the outgoing telephone numbers of the MLPPP
-host.

-3. Beta Change Summaries and Miscellaneous Notes
-------------------------------------------------
-When using the "scctrl" utility to upload firmware revisions on the board,
-please note that the byte count displayed at the end of the operation may be
-different from the total number of bytes in the "dcbfwn.nn.sr" file. Please
-disregard the displayed byte count.
-
-It was noted that in Beta Release 1, the module would fail to load and result
-in a segmentation fault when 'insmod'ed. This problem was created when one of
-the isdn4linux parameters, (isdn_ctrl, data field) was filled in. In some
-cases, this data field was NULL, and was left unchecked, so when it was
-referenced... segv. The bug has been fixed around line 63-68 of event.c.
