ctau(4)

NAME

ctau - driver for synchronous Cronyx Tau WAN adapters

SYNOPSIS

device ctau
Additional options:
device sppp
options NETGRAPH
options NETGRAPH_CRONYX
In /boot/device.hints:
hint.ctau.0.at="isa"
hint.ctau.0.port="0x240"
hint.ctau.0.irq="15"
hint.ctau.0.drq="7"

DESCRIPTION

The ctau driver needs either sppp(4) or netgraph(4). Which

one to use is
determined by the NETGRAPH_CRONYX option. If this option is

present in
your kernel configuration file, the ctau driver will be com

piled with
netgraph(4) support. Otherwise, it will be compiled with

sppp(4) support.

The base I/O port address specified in /boot/device.hints

must match the
port address set by the jumpers on the board. The DMA I/O

channel and
interrupt request numbers are configured by software at

adapter initialization. Legal values are:

Port: 0x200, 0x220, 0x240, 0x260, 0x280, 0x2a0, 0x2c0,

0x2e0, 0x300,

0x320, 0x340, 0x360, 0x380, 0x3a0, 0x3c0, 0x3e0

IRQ: 3, 5, 7, 10, 11, 12, 15
DMA: 5, 6, 7

The ctau driver supports autodetection. As for all non-PNP

hardware,
using autodetection could lead to some potential problems

with other
devices during the hardware detection process. It is always

better to
specify hardware resources manually.

Refer to sconfig(8) for information about the ctau adapter

configuration.
