cx -- driver for synchronous/asynchronous Cronyx-Sigma WAN adapters
The cx driver needs either sppp(4) or netgraph(4). Which one to use is
determined by NETGRAPH_CRONYX option. If this option is present in your
kernel configuration file, the cx driver will be compiled with
netgraph(4) support, else driver 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 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
of autodetection could lead to some potential problems with other devices
during detection of hardware. It is alway better to specify hardware
Refere to sconfig(8) for information about the cx adapter configuration.
cx(4), sppp(4), ifconfig(8), sconfig(8), spppcontrol(8)
The cx driver was updated in FreeBSD 5.2. In most of previous versions
of FreeBSD the cx driver is out of date. The cx driver for previous versions
of FreeBSD is available from http://www.cronyx.ru/.
