LTmodem Tracking Page June 4, 2001 update

Statement of Purpose -  to Exist as little as possible.
Acknowledgement Agere Systems, Inc,(AS)  provided the predecessor linux599.zip kit with proprietary DSP (digital signal processor) code.  Enhancements in both ease of installation and functionality are reflected in the linux599.zip --> ltmodem-5.99 kit transition.  Details are in:
Release 5.99a   -  What is new and Who.
Who should upgrade  -  don't rush, with exceptions.
The Configure implementation - easier for Newbies.
Garments around the Source - adaptiveness and added utility.

Both driver compiler and driver installer kits are downloaded from Canada or Germany.
There is a  Polish Linux distribution, with a slighjtly modified compiler kit.

Nomenclature issues: The compiled  5.99 drivers from ltmodem-5.99 kits are named lt_modem.o and lt_serial.o and use a node /dev/ttyLT0 c 62 64
In the prior 5.78 release, functionality was combined a single ltmodem.o driver.
The drivers compiled from the AS linux599.zip are named ltmodem.oandltserial.o and use node:
/dev/ttyS14 c 62 78.  They lack support for the Forced parameters and other enhancements crucial to some of successes described below.  Each driver pair will only be functional with its own /dev/Node.

Easy installations are most common;
     Mandrake 8.0 --
     Acer laptop 514TE ---
     Siemens laptop (lifeserie c) with ltmodem/intel_ethernet express combination.

Some diligence effort is needed with particular hardware or Linux distributions.
     A 3rd Forcing parameter is needed, as in 5.78e and 5.78f releases.

                   options lt_modem Forced=3,0x130,0x2F8 set in /etc/modules.conf
     Acer Extensa 501 laptop  - Forced=3,0x108,0x2e8 with with details for RedHat 7.1.
     Acer Extensa 500T            Forced=3,0x108,0x2e8
     Toshiba 530CDT                Forced=3,0x130,0x2f 8
     Some IBM Thinkpads have Lucent modems -  but the drivers  provided are the now dated release 5.95.
     Thinkpad i1400 --
       
PCMCIA Lucent chip modem guidance:
     32 bit  Cardbus, recognized as anamalous memory.
     16 bit  Forced=3,0xbc,0x2f8 , usage of wvdialconf. Only lt_modem.o is necessary.  In contrast to 2.2.nn PCMCIA support, for 2.4.nn kernel compiles, serial_cs.o must be specified within # PCMCIA character devices: CONFIG_PCMCIA_SERIAL_CS=m

Problem solving

Information gathering instructions, before querying the List for help.

Driver compilation failures are Most Commonly due to inadequate kernel-header resources.  Read revelant sections of 1ST-READ and  DOCs/compile failures.

Using fixscript to bypass minor unresolved symbols errors after the a successfull drivers compilation.
    Explanation towards the end of 1ST-READ, in DOCs/  and Utils/

'"ALIASLINES"'  complaint while loading drivers. A bug you can easily bypass.

DOCs/Insert-param.html directs the checks to do if modem drivers do not initially load.

isa-pnp line in /etc/modules.conf  is not required

Resolution of audo card conflict. -- case report

Post install issues -- from Jacques Goldberg

wvdial configuration - a temporary symbolic link is necessary

DOCs errors -

Status of the id= 0x420 Xircom/lucent modem suport. Support for these modems has not yet been achieved, but a resolution of the problems is being actively pursued.

Modem sounds are not produced in a Small Minority of the 5.99 installations, in which functionality is otherwise fine. For one such system, use of the older archived 5.95 release did Restore sound.

A modem string with X2  only increases modem to CPU speed, not necesssarily CONNECT speed.

Co-existence of ethernet and ppp - Jacques Golderg comments.

Internet navigation , compare PING tests with IP NumericAddress and correponding NameAddress.
