-Linux Quicknet-Drivers-Howto
-Quicknet Technologies, Inc. (www.quicknet.net)
-Version 0.3.4 December 18, 1999
-
-1.0 Introduction
-
-This document describes the first GPL release version of the Linux
-driver for the Quicknet Internet PhoneJACK and Internet LineJACK
-cards. More information about these cards is available at
-www.quicknet.net. The driver version discussed in this document is
-0.3.4.
-
-These cards offer nice telco style interfaces to use your standard
-telephone/key system/PBX as the user interface for VoIP applications.
-The Internet LineJACK also offers PSTN connectivity for a single line
-Internet to PSTN gateway. Of course, you can add more than one card
-to a system to obtain multi-line functionality. At this time, the
-driver supports the POTS port on both the Internet PhoneJACK and the
-Internet LineJACK, but the PSTN port on the latter card is not yet
-supported.
-
-This document, and the drivers for the cards, are intended for a
-limited audience that includes technically capable programmers who
-would like to experiment with Quicknet cards. The drivers are
-considered in ALPHA status and are not yet considered stable enough
-for general, widespread use in an unlimited audience.
-
-That's worth saying again:
-
-THE LINUX DRIVERS FOR QUICKNET CARDS ARE PRESENTLY IN A ALPHA STATE
-AND SHOULD NOT BE CONSIDERED AS READY FOR NORMAL WIDESPREAD USE.
-
-They are released early in the spirit of Internet development and to
-make this technology available to innovators who would benefit from
-early exposure.
-
-When we promote the device driver to "beta" level it will be
-considered ready for non-programmer, non-technical users. Until then,
-please be aware that these drivers may not be stable and may affect
-the performance of your system.
-
-
-1.1 Latest Additions/Improvements
-
-The 0.3.4 version of the driver is the first GPL release. Several
-features had to be removed from the prior binary only module, mostly
-for reasons of Intellectual Property rights. We can't release
-information that is not ours - so certain aspects of the driver had to
-be removed to protect the rights of others.
-
-Specifically, very old Internet PhoneJACK cards have non-standard
-G.723.1 codecs (due to the early nature of the DSPs in those days).
-The auto-conversion code to bring those cards into compliance with
-today's standards is available as a binary only module to those people
-needing it. If you bought your card after 1997 or so, you are OK -
-it's only the very old cards that are affected.
-
-Also, the code to download G.728/G.729/G.729a codecs to the DSP is
-available as a binary only module as well. This IP is not ours to
-release.
-
-Hooks are built into the GPL driver to allow it to work with other
-companion modules that are completely separate from this module.

-Disclaimer
-
-Much of the info in this HOWTO is early information released by
-Quicknet Technologies, Inc. for the express purpose of allowing early
-testing and use of the Linux drivers developed for their products.
-While every attempt has been made to be thorough, complete and
-accurate, the information contained here may be unreliable and there
-are likely a number of errors in this document. Please let the
-maintainer know about them. Since this is free documentation, it
-should be obvious that neither I nor previous authors can be held
-legally responsible for any errors.

-
-1.3 Future Plans: You Can Help
-
-Please let the maintainer know of any errors in facts, opinions,
-logic, spelling, grammar, clarity, links, etc. But first, if the date
-is over a month old, check to see that you have the latest
-version. Please send any info that you think belongs in this document.
-
-You can also contribute code and/or bug-fixes for the sample
-applications.
-
-
-1.4 Where to get things
-
-Info on latest versions of the driver are here:
-
-http://web.archive.org/web/*/http://www.quicknet.net/develop.htm
-
-1.5 Mailing List
-
-Quicknet operates a mailing list to provide a public forum on using
-these drivers.
-
-To subscribe to the linux-sdk mailing list, send an email to:
-
- majordomo@linux.quicknet.net
-
-In the body of the email, type:
-
- subscribe linux-sdk <your-email-address>
-
-Please delete any signature block that you would normally add to the
-bottom of your email - it tends to confuse majordomo.
-
-To send mail to the list, address your mail to
-
- linux-sdk@linux.quicknet.net
-
-Your message will go out to everyone on the list.
-
-To unsubscribe to the linux-sdk mailing list, send an email to:
-
- majordomo@linux.quicknet.net
-
-In the body of the email, type:
-
- unsubscribe linux-sdk <your-email-address>

-
-
-2.0 Requirements
-
-2.1 Quicknet Card(s)
-
-You will need at least one Internet PhoneJACK or Internet LineJACK
-cards. These are ISA or PCI bus devices that use Plug-n-Play for
-configuration, and use no IRQs. The driver will support up to 16
-cards in any one system, of any mix between the two types.
-
-Note that you will need two cards to do any useful testing alone, since
-you will need a card on both ends of the connection. Of course, if
-you are doing collaborative work, perhaps your friends or coworkers
-have cards too. If not, we'll gladly sell them some!
-
-
-2.2 ISAPNP
-
-Since the Quicknet cards are Plug-n-Play devices, you will need the
-isapnp tools package to configure the cards, or you can use the isapnp
-module to autoconfigure them. The former package probably came with
-your Linux distribution. Documentation on this package is available
-online at:
-
-http://mailer.wiwi.uni-marburg.de/linux/LDP/HOWTO/Plug-and-Play-HOWTO.html
-
-The isapnp autoconfiguration is available on the Quicknet website at:
-
- http://www.quicknet.net/develop.htm
-
-though it may be in the kernel by the time you read this.
-
-
-3.0 Card Configuration
-
-If you did not get your drivers as part of the linux kernel, do the
-following to install them:
-
- a. untar the distribution file. We use the following command:
- tar -xvzf ixj-0.x.x.tgz
-
-This creates a subdirectory holding all the necessary files. Go to that
-subdirectory.
-
- b. run the "ixj_dev_create" script to remove any stray device
-files left in the /dev directory, and to create the new officially
-designated device files. Note that the old devices were called
-/dev/ixj, and the new method uses /dev/phone.
-
- c. type "make;make install" - this will compile and install the
-module.
-
- d. type "depmod -av" to rebuild all your kernel version dependencies.
-
- e. if you are using the isapnp module to configure the cards
- automatically, then skip to step f. Otherwise, ensure that you
- have run the isapnp configuration utility to properly configure
- the cards.
-
- e1. The Internet PhoneJACK has one configuration register that
- requires 16 IO ports. The Internet LineJACK card has two
- configuration registers and isapnp reports that IO 0
- requires 16 IO ports and IO 1 requires 8. The Quicknet
- driver assumes that these registers are configured to be
- contiguous, i.e. if IO 0 is set to 0x340 then IO 1 should
- be set to 0x350.
-
- Make sure that none of the cards overlap if you have
- multiple cards in the system.
-
- If you are new to the isapnp tools, you can jumpstart
- yourself by doing the following:
-
- e2. go to the /etc directory and run pnpdump to get a blank
- isapnp.conf file.
-
- pnpdump > /etc/isapnp.conf
-
- e3. edit the /etc/isapnp.conf file to set the IO warnings and
- the register IO addresses. The IO warnings means that you
- should find the line in the file that looks like this:
-
- (CONFLICT (IO FATAL)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING
-
- and you should edit the line to look like this:
-
- (CONFLICT (IO WARNING)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) #
- or WARNING
-
- The next step is to set the IO port addresses. The issue
- here is that isapnp does not identify all of the ports out
- there. Specifically any device that does not have a driver
- or module loaded by Linux will not be registered. This
- includes older sound cards and network cards. We have
- found that the IO port 0x300 is often used even though
- isapnp claims that no-one is using those ports. We
- recommend that for a single card installation that port
- 0x340 (and 0x350) be used. The IO port line should change
- from this:
-
- (IO 0 (SIZE 16) (BASE 0x0300) (CHECK))
-
- to this:
-
- (IO 0 (SIZE 16) (BASE 0x0340) )
-
- e4. if you have multiple Quicknet cards, make sure that you do
- not have any overlaps. Be especially careful if you are
- mixing Internet PhoneJACK and Internet LineJACK cards in
- the same system. In these cases we recommend moving the
- IO port addresses to the 0x400 block. Please note that on
- a few machines the 0x400 series are used. Feel free to
- experiment with other addresses. Our cards have been
- proven to work using IO addresses of up to 0xFF0.
-
- e5. the last step is to uncomment the activation line so the
- drivers will be associated with the port. This means the
- line (immediately below) the IO line should go from this:
-
- # (ACT Y)
-
- to this:
-
- (ACT Y)
-
- Once you have finished editing the isapnp.conf file you
- must submit it into the pnp driverconfigure the cards.
- This is done using the following command:
-
- isapnp isapnp.conf
-
- If this works you should see a line that identifies the
- Quicknet device, the IO port(s) chosen, and a message
- "Enabled OK".
-
- f. if you are loading the module by hand, use insmod. An example
-of this would look like this:
-
- insmod phonedev
- insmod ixj dspio=0x320,0x310 xio=0,0x330
-
-Then verify the module loaded by running lsmod. If you are not using a
-module that matches your kernel version, you may need to "force" the
-load using the -f option in the insmod command.
-
- insmod phonedev
- insmod -f ixj dspio=0x320,0x310 xio=0,0x330
-
-
-If you are using isapnp to autoconfigure your card, then you do NOT
-need any of the above, though you need to use depmod to load the
-driver, like this:
-
- depmod ixj
-
-which will result in the needed drivers getting loaded automatically.
-
- g. if you are planning on having the kernel automatically request
-the module for you, then you need to edit /etc/conf.modules and add the
-following lines:
-
- options ixj dspio=0x340 xio=0x330 ixjdebug=0
-
-If you do this, then when you execute an application that uses the
-module the kernel will request that it is loaded.
-
- h. if you want non-root users to be able to read and write to the
-ixj devices (this is a good idea!) you should do the following:
-
- - decide upon a group name to use and create that group if
- needed. Add the user names to that group that you wish to
- have access to the device. For example, we typically will
- create a group named "ixj" in /etc/group and add all users
- to that group that we want to run software that can use the
- ixjX devices.
-
- - change the permissions on the device files, like this:
-
- chgrp ixj /dev/ixj*
- chmod 660 /dev/ixj*
-
-Once this is done, then non-root users should be able to use the
-devices. If you have enabled autoloading of modules, then the user
-should be able to open the device and have the module loaded
-automatically for them.
-
-
-4.0 Driver Installation problems.
-
-We have tested these drivers on the 2.2.9, 2.2.10, 2.2.12, and 2.2.13 kernels
-and in all cases have eventually been able to get the drivers to load and
-run. We have found four types of problems that prevent this from happening.
-The problems and solutions are:
-
- a. A step was missed in the installation. Go back and use section 3
-as a checklist. Many people miss running the ixj_dev_create script and thus
-never load the device names into the filesystem.
-
- b. The kernel is inconsistently linked. We have found this problem in
-the Out Of the Box installation of several distributions. The symptoms
-are that neither driver will load, and that the unknown symbols include "jiffy"
-and "kmalloc". The solution is to recompile both the kernel and the
-modules. The command string for the final compile looks like this:
-
- In the kernel directory:
- 1. cp .config /tmp
- 2. make mrproper
- 3. cp /tmp/.config .
- 4. make clean;make bzImage;make modules;make modules_install
-
-This rebuilds both the kernel and all the modules and makes sure they all
-have the same linkages. This generally solves the problem once the new
-kernel is installed and the system rebooted.
-
- c. The kernel has been patched, then unpatched. This happens when
-someone decides to use an earlier kernel after they load a later kernel.
-The symptoms are proceeding through all three above steps and still not
-being able to load the driver. What has happened is that the generated
-header files are out of sync with the kernel itself. The solution is
-to recompile (again) using "make mrproper". This will remove and then
-regenerate all the necessary header files. Once this is done, then you
-need to install and reboot the kernel. We have not seen any problem
-loading one of our drivers after this treatment.
-
-5.0 Known Limitations
-
-We cannot currently play "dial-tone" and listen for DTMF digits at the
-same time using the ISA PhoneJACK. This is a bug in the 8020 DSP chip
-used on that product. All other Quicknet products function normally
-in this regard. We have a work-around, but it's not done yet. Until
-then, if you want dial-tone, you can always play a recorded dial-tone
-sound into the audio until you have gathered the DTMF digits.
