NAME

     sbsh - Granch SBNI16 SHDSL modem device driver

SYNOPSIS

     device sbsh

DESCRIPTION

     The sbsh driver provides support for an internal PCI modem SBNI16-SHDSL.
     A device is introduced to the OS as a common Ethernet-like network card
     which must be configured with ifconfig(8) (all standard network interface
     parameters could be set).  Modem-specific parameters (master/slave mode,
     line rate, etc.) must be set with the sb16config utility before interface
     activation.

FILES

     The sources for the driver reside in:

     /sys/dev/sbsh/if_sbsh.c
     /sys/dev/sbsh/if_sbshreg.h
