General Information
This is the Chipset family which made Smart Link’s (SL) name, and got them into their current position of being the major supplier of (cheap) modems to the computer industry.

SL are not really a chipset manufacturer--STMicro supply the silicon--but rather a software, design & marketing company. As the hardware on the modem card provides only interface functions to computer & telephone line, all the hard work of being a modem is done by software within the OS. In theory this can, of course, be any OS on any computer. Currently, SL provide Linux- & Windows-hosted drivers for every major consumer computing platform.

The key to SL’s success lies in the following words: normally, the section that you are reading right now would refer you to your computer’s M/B manufacturer, which would mean finding a different page. Smart Link truly are ‘Smart’, as they provide drivers which are generic for both PCI & AC-Link designs across all MBs. The downside is that the drivers are a touch on the large side. Here are the key aspects:
  • AC-Link modems are normally specific to a MB chipset.
  • The EEPROM IDs which identify them to drivers are based on the manufacturer of the M/B, not the modem.
  • In practical terms, the items above usually mean:
    1. drivers & info are found via the M/B mfc, not the modem mfc.
    2. drivers are specific not only to the M/B mfc, but also to the specific M/B.
    3. a modem cannot be moved from one M/B to another.
    4. end result: drivers & info are difficult--often impossible--to find
  • SL have taken the trouble to provide single drivers which work with ALL M/Bs for which they are verified

Known Problems
v3.60.03: Matthew advises Windows XP connections considerably improved from erratic 49.3/33.6k (with 3.00e) to a steady 48k. Matthew also reports “one odd thing was that with the new driver, echoing can be heard while it dials”.
v3.04.00: Karen Tamrazyan advises AT#UD (Unimodem Diagnostics) are not reporting correctly.
v2.92.04ND: (Early V.92) odd connection problems with non-V.92 ISPs, such as AOL. Typical symptoms are a dropped connection with a call-waiting notification - particularly strange if your line does not have this feature active! Fix: drop to V.34. Use Safe-Mode 2 (Modem Helper in Modem Settings in Control Panel).
v2.92.04: (Windows XP) Simon Zerafa advises resolves issues with BSOD’s and PC reboots when using AOL v7.0 (see also other AOL 7 problems).
  • Windows 2000 systems need at least 64 MB RAM - less may result in system crashes.
  • Wake-up-on-ring (and possibly power-down) does not work with some motherboards - SL blames the M/B designs.
  • AMR Cards may be set to the wrong mode - they are either Primary- or Secondary-Mode designs, depending both on the M/B & the sound card fitted (see FAQ #10 - this site).
  • no/dropped/V34 connections may be caused by certain graphics cards hogging the PCI bus (Smart Link fingers 24 graphics cards at FAQ #19 - this site) - drop hardware acceleration until the problem goes:- see Control Panel, Display, Settings, Advanced, Performance
  • no dial tone - try putting ATX3 in Extra Settings
Supplied with latest drivers.

Mfc: the company no longer makes/supplies modems and/or their chipsets, or has been taken over, or otherwise fallen into commercial Tophet.

Modem: it is no longer in production.

Chip, Chipset, Family or Family-Type: it is no longer produced at the Foundry.

In short, the item marked with a has shuffled off this mortal coil, it has gone to meet it’s maker, to sing with the choir invisible; it is, not to put too fine a point upon it, an ex-modem (-Mfc, -Chip, -Chipset, -Family or -Type).

Site Info, History & Page Stats

These pages are a LAMP-development of the original Modem-Help, UK site (most of the old HTML pages still exist, but havn’t been updated for quite some time). That site, in it’s turn, was a transfer from the first html site on free-pages at Freeserve (sadly, now gone). The current format allows superb search facilities, customisation by Registered members, plus is quick ‘n’ easy to update.

Diligently put together in the UK by Alex Kemp. All efforts have been taken to ensure the veracity of what is written - if you know of any errors or omissions then please let us know.
