General Information
- Originated by Conexant on 20 April, 1999 this was a development of the enormously successful, Rockwell-originated HSF chipsets. The main innovation was the use of the “SmartDAA” silicon chip. This latter had the advantages of zero power-draw from the telephone line, elimination of mechanical components, simple worldwide homologation of the entire chipset, improved lightning protection and, of course, meant that Conexant could sell the modem manufacturers a DAA.
The SmartHSF was pin-compatible with the SmartHCF chipset. This allowed one set of development work to produce two modems. The SmartHCF was sold at a premium compared to the SmartHSF--this is the inferior chipset, as it is absent of a DSP, relying on the host-cpu to perform all modem functions--although the difference in parts-cost is negligible.
The SmartHCF/M is another variant of this same chipset, but designed for mobile (mini-PCI, Cardbus) computers.

Known Problems
- (Windows XP, 2000, Millennium): the phone line may be disconnected if a DVD/CD-ROM drive is configured to PIO mode (the default on some systems) and is in use. Configure to DMA mode (Device Manager, usually IDE ATA/ATAPI Channels, Primary and/or Secondary channel). Extra info: PIO is an old transfer-mode which ties up the CPU whilst moving data bit-by-bit across the computer bus; DMA uses a DMA-controller to rapidly shift blocks of data in parallel with the CPU, and was explicitly designed to solve the congestion problems caused by PIO transfers.

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 (still maintained, but just re-direction pages to this site). 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.
