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 compiled 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.

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the previous versions of FreeBSD the cx driver is out of date.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
