http://lists.opensuse.org/opensuse/2007-01/msg00204.html is the
PCTEL 2304WT v.92 MDC mailing list thread which lead to my submitting this.

This is not my Dell C610/C640 laptop. Its owner entrusted me to solve his
problem with W2K no longer recognizing the modem after he randomly deleted
various files following failure to connect to his ISP after his ISP's phone
numbers went bad. I repartitioned to provide space for SUSE, then installed
XP using the Dell custom XP installation CD, which failed to find the modem.
After several attempts to install various drivers without success, not knowing
that the ISP phone numbers were bad and with the XP driver always failing to
make any audible indication that it was doing anything at all. I proceeded
to install SUSE 10.0 from the boxed DVD.

The modem worked immediately on completion of the 10.0 installation, though
I still had no usable connection from the bad phone numbers, so I rebooted
XP. Eventually I found the R53654 driver on the Dell web site. Once that was
installed I managed to find out about the bad phone numbers, and XP was then
able to connect to his ISP.

Next I installed OpenSUSE 10.2 from HTTP. The modem failed initial testing,
unlike 10.0. I got the 10.2 boxed DVD and tried again, failing in same manner.
So, here's the ModemData.txt file.

Modem or host audio card candidates have firmware information:

 The PCI slot 00:1f.6 of the modem card may be disabled early in
 a bootup process,  but then enabled later. If modem drivers load
 but the  modem is not responsive, read Bootup.txt about possible fixes.
 Send dmesg.txt along with ModemData.txt to discuss@xxxxxxxxxxxxx
 if help is needed.

 For candidate modem in PCI bus:  00:1f.6
   Class 0703: 8086:2486 Modem: Intel Corporation 82801CA/CAM AC'97 Modem Controller
      Primary PCI_id  8086:2486
    Subsystem PCI_id  134d:4c21 , 134d is an ALSA compatible identification
    Softmodem codec or Vendor from diagnostics: SIL21, a Pctel type.
                              from    Archives: SIL21, a Pctel type.


 Lacking a dsp (digital signal processing) chip, the modem is a software
 intensive or "softmodem" type. Its primary controller manages the traffic
 with the CPU. But the software needed is specified in the Subsystem.
 -----------------------------------------
Support type needed or chipset:	slmodemd

 An ALSA (Advanced Linux Sound Architecture) modem driver:  snd-intel8x0m
 provides Low Level support enabling contact with the modem hardware.
 For all BUT Conexant chip soft modems (using hsfmodem software)
 complementary High Level support is through a Smartlink utility:  slmodemd

 Download from http://linmodems.technion.ac.il/packages/smartlink/
 the package SLMODEMD.gcc4.tar.gz having a compiled slmodemd. Unpack under Linux with:
 	$ tar zxf SLMODEMD.gcc4.tar.gz
 and read instructions therein. But briefly, the modem is setup with command:
 	 slmodemd -c YOUR_COUNTRY --alsa modem:1
 reporting dynamic creation of ports:
	/dev/ttySL0 --> /dev/pts/N   , with N some number
 Read Smartlink.txt and Modem/YourSystem.txt for follow through guidance.

 Already loaded into the kernel is snd-intel8x0m and audio drivers it depends on,
 displayed by:	lsmod | grep snd_intel8x0m

The diagnostic outputs for this softmodem section have their raw information in
folders and text files under /proc/asound/ which you can browse. The information
is from files:
	/proc/asound/pcm

00-00: Intel ICH : Intel 82801CA-ICH3 : playback 1 : capture 1

	/proc/asound/card1/codec97#0/mc97#1-1+regs

which were translated from hexadecimal code into:  SIL21

and from the command:
	aplay -l | grep -i modem

 The base of the UDEV device file system is: /dev/.udev

 The kernel was compiled with gcc version 4.1.2 and a compiler is not installed

 Kernel-header resources needed for compiling are not manifestly ready!

 If compiling is necessary packages must be installed, providing:
	gcc-4.1  kernel-source-2.6.18.2-34-default


Checking pppd properties:
	-rwxr-xr-x 1 root dialout 295488 Nov 25 14:50 /usr/sbin/pppd

In case of an "error 17" "serial loopback" problem, see:
    http://phep2.technion.ac.il/linmodems/archive-sixth/msg02637.html

To enable dialout without Root permission do:
	$ su - root  (not for Ubuntu)
         chmod a+x /usr/sbin/pppd
or under Ubuntu related Linuxes
	 chmod a+x /usr/sbin/pppd

Which can interfere with Browser naviagation.
