|
|
.Sh SYNOPSIS
|
|
.Cd "device sbsh"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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
|
|
.Xr ifconfig 8
|
|
(all standard network interface parameters could be set).
|
|
Modem-specific
|
|
parameters (master/slave mode, line rate, etc.) must be set with the
|
|
.Nm sb16config
|
|
utility before interface activation.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "sbsh%d: couldn't map memory"
