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.
