  9. --------------------------  System information ----------------------------
  10. CPU=i686,  Linux Mint Cassandra
  11. Linux version 2.6.20-16-generic ([email protected]) (gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)) #2 SMP Thu Jun 7 20:19:32 UTC 2007
  12.  scanModem update of:  2007-20-07
  13.  
  14.  
  15.  There are no blacklisted modem drivers in /etc/modprobe*  files
  16.  
  17. The Advanced Linux Sound Architecture (ALSA) packages providing audio support on your System,
  18. also includes drivers for some modems. High Definition Audio (HDA) cards can themselves host
  19. a softmodem chipset, with both audio+modem supported by a snd-hda-intel driver.
  20. The ALSA diagnostics are written during bootup to /proc/asound/ folders.
  21.  
  22. Summary card and chipset information is in:
  23. /proc/asound/cards:
  24.  0 [Intel          ]: HDA-Intel - HDA Intel
  25.                       HDA Intel at 0xd8500000 irq 16
  26.  1 [CMI8738MC6     ]: CMI8738-MC6 - C-Media PCI CMI8738-MC6
  27.                       C-Media PCI CMI8738-MC6 (model 55) at 0xc800, irq 22
  28.  
  29. /proc/asound/pcm:
  30. 00-02: ALC880 Analog : ALC880 Analog : capture 2

  33. 01-01: CMI8738-MC6 : C-Media PCI 2nd DAC : playback 1
  34. 01-00: CMI8738-MC6 : C-Media PCI DAC/ADC : playback 1 : capture 1
  35.  
  36.  A copy of /proc/asound had been copied to Modem/ALSAroot.tgz
  37.  PCI slot 00:1b.0 has a High Definition Audio Card
  38. USB modem not detected by lsusb
  39.  
  40. For candidate card, firmware information and bootup diagnostics are:
  41.  
  42.  PCI slot       PCI ID  SubsystemID      Name
  43.  ----------     ---------    ---------   --------------
  44.  06:01.0        14f1:2f00       14f1:2004      Communication controller: Conexant HSF 56k HSFi Modem
  45.  
  46.  Modem interrupt assignment and sharing:
  47.  --- Bootup diagnostics for card in PCI slot 06:01.0 ----
  48. For candidate card, firmware information and bootup diagnostics are:
  49.  
  50.  PCI slot       PCI ID  SubsystemID      Name
  51.  ----------     ---------    ---------   --------------

  58. [   40.898592] PCI: Setting latency timer of device 0000:00:1b.0 to 64
  59.  
  60.  === Finished modem firmware and bootup diagnostics section. ===
  61.  === Next deducing cogent software ===
  62.  
  63.   The High Defintion Audio card with PCI ID 8086:2668 may host a soft modem chip.
  64.  The NotDetermined is not supported by this kernel.
  65.  
  66. There is candidate modem software.
  67.  
  68.  For candidate modem in PCI bus:  00:1b.0
  69.    Class 0403: 8086:2668 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW
  70.       Primary PCI_id  8086:2668
  71.     Subsystem PCI_id  8086:e307
  72.     Softmodem codec or chipset from diagnostics:
  73.                                from    Archives:
  74.                        
  75.  
  76.  Lacking a dsp (digital signal processing) chip, the modem is a software
  77.  intensive or "softmodem" type. Its primary controller manages the traffic
  78.  with the CPU. But the software needed is specified in the Subsystem.
  79.  -----------------------------------------
  80. Support type needed or chipset: 
  81.  
  82. Support can likely be achieved through two mutually exclusive alternatives:
  83. 1) The hsfmodem software for Conexant chipset modems: Read Conexant.txt
  84. The following ALSA alternative CANNOT work with Conexant modems.
  85.  
  86. 2) An ALSA modem driver plus slmodemd.  Read Smartlink.txt for details, and
  87. to test get the package SLMODEMD.gcc4.1.tar.gz from: 
  88.         http://linmodems.technion.ac.il/packages/smartlink/
  89.  
  90.  
  91. Writing Intel.txt
  92.  
  93. For owners of a Dell PCs with Conexant HSF modems, a driver source package with full speed enabled is available, but requires driver compiling. Read Conexant.txt
  94.  
  95.  Read Conexant.txt

  100. ============ end Smartlink section =====================
  101.  
  102.  For candidate modem in PCI bus:  06:01.0
  103.    Class 0780: 14f1:2f00 Communication controller: Conexant HSF 56k HSFi Modem
  104.       Primary PCI_id  14f1:2f00
  105.  Support type needed or chipset:        hsfmodem
  106.  
  107.  
  108.  
  109. For owners of a Dell PCs with Conexant HSF modems, a driver source package with full speed enabled is available, but requires driver compiling. Read Conexant.txt
  110.  
  111.  The hsfmodem package serves a great variety of Conexant chipset modems.
  112.  Start at  http://www.linuxant.com/drivers/hsf for
  113.  eventually download of a hsfmodem-SomeVersion.zip  package with
  114.  SomeVersion containing your kernel_version 2.6.20-16-generic  in the filename if possible.
  115.  These packages have compiled drivers. Otherwise download the generic
  116.  hsfmodem-Version.tar.gz  package. Its usage will require compiling.
  117.  
  118.  Read Conexant.txt
  119.  
  120. Writing Conexant.txt
  121.  
  122.  
  123.  Completed candidate modem analyses.
  124.  
  125.  The base of the UDEV device file system is: /dev/.udev
  126.  
  127.  Versions adequately match for the compiler installed: 4.1.2
  128.              and the compiler used in kernel assembly: 4.1.2
  129.  
  130.  
  131.  
  132.  Minimal compiling resources appear complete:
  133.    make utility - /usr/bin/make
  134.    Compiler version 4.1
  135.    linuc_headers base folder /lib/modules/2.6.20-16-generic/build
  136.  
  137.  However some compilations and executable functions may need additional files,
  138.  in the FileNames.h (so called kernel "h"eaders) collection installed in  /usr/include/ .
  139.  For martian_modem, additional required packages are libc6-dev (and for Debian/Ubuntu,  linux-libc-dev). The also required headers of package libc6 are commonly installed by default.
  140.  
  141.  
  142. For Debian and some related distributions, a package kernel-kbuild-2.6-20 may be needed to support driver compiling
  143.  
  144.  
  145. If a driver compilation fails, with message including some lack of some FileName.h (stdio.h for example), then
  146. Some additional kernel-header files need installation to /usr/include. The minimal additional packages are libc6-dev
  147. and any of its dependents, under Ubuntu linux-libc-dev
  148.  
  149. If an alternate ethernet connection is available,
  150. $  apt-get update
  151. $  apt-get -s install linux-kernel-devel
  152. will install needed pacakage
  153. For Debian/Ubuntu related distributions, run the following command to display the needed package list:
  154.  
  155. Otherwise packages have to be found through http://packages.ubuntu.com
  156. Once downloaded and transferred into a Linux partition,
  157. they can be installed alltogether with:
  158. $ sudo dpkg -i *.deb
  159.  
  160.  
  161. Checking pppd properties:
  162.         -rwsr-xr-- 1 root dip 269224 2007-04-05 11:41 /usr/sbin/pppd
  163.  
  164. In case of an "error 17" "serial loopback" problem, see:
  165.     http://phep2.technion.ac.il/linmodems/archive-sixth/msg02637.html
  166.  
  167. To enable dialout without Root permission do:
  168.         $ su - root  (not for Ubuntu)
  169.          chmod a+x /usr/sbin/pppd
  170. or under Ubuntu related Linuxes
  171.          chmod a+x /usr/sbin/pppd
  172.  
  173. Checking settings of:   /etc/ppp/options
  174. asyncmap 0
  175. noauth
  176. crtscts
  177. lock
  178. hide-password
  179. modem
  180. proxyarp
  181. lcp-echo-interval 30
  182. lcp-echo-failure 4
  183. noipx
  184.  
  185. In case of a message like:
  186.    Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
  187. see http://linmodems.technion.ac.il/bigarch/archive-sixth/msg04656.html
  188.  
  189. Read Modem/YourSystem.txt concerning other COMM channels: eth0 eth0:avah
  190. Which can interfere with Browser naviagation.
  191.  
  192.  Don't worry about the following, it is for the experts
  193.  should trouble shooting be necessary.

  199. slmodemd created symbolic link /dev/ttySL0: 
  200.      Within /etc/udev/ files:
