cx(4)

NAME

cx - driver for synchronous/asynchronous Cronyx Sigma WAN

adapters

SYNOPSIS

To  compile this driver into the kernel, place the following
line in your
kernel configuration file:
      device cx
Alternatively, to load the driver as a module at boot  time,
place the
following line in loader.conf(5):
      if_cx_load="YES"
Additional options:
device sppp
options NETGRAPH
options NETGRAPH_CRONYX
In /boot/device.hints:
hint.cx.0.at="isa"
hint.cx.0.port="0x240"
hint.cx.0.irq="15"
hint.cx.0.drq="7"

DESCRIPTION

The cx 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 cx 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: 0x240, 0x260, 0x280, 0x300, 0x320, 0x380
IRQ: 3, 5, 7, 10, 11, 12, 15
DMA: 5, 6, 7

The cx 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 cx adapter

configuration.

HARDWARE

HISTORY

The cx driver was updated in FreeBSD 5.2 and FreeBSD 4.10.

In most of
the previous versions of FreeBSD the cx driver is out of

date. The cx
driver for previous versions of FreeBSD is available from
