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):
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.
HARDWARE¶
The
cx
driver supports the following cards:
- Cronyx Sigma-22, Sigma-24

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driver is out of date.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
