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.

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     cx driver is out of date.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
     http://www.cronyx.ru/.
