PCI bus soft (HSP) modem

Identifiers

Identified versions:

BCM4210 - HomePNA (added circuitry for modem)
BCM4211 - HomePNA + V.90 soft modem
BCM4212 - V.90/V.92 soft modem only(?)
These are the Gateway "Palmer" modems. This may be a custom chipset for Gateway.
BCM4413 - HomePNA + V.90 soft modem + 10/100 Ethernet

The BCM4212 chipset resembles the PCTel 1789 chipset.

Linux support

Dell has released binary kernel modules for their BCM4212-based modem. It is not known whether they can be adapted to work with the entire BCM421x family.

Cengiz Gunay has adapted these binary kernel modules to newer versions of the Linux kernel: RPMs

Components

    BCM4211KTF  HomePNA + V.90 soft modem    144-pin TQFP standard package
    BCM4211KTL  HomePNA + V.90 soft modem    144-pin TQFP thin package for MiniPCI
    BCM4212      V.90/V.92 soft modem
