NAME    [Toc]    [Back]

     cx -- driver for synchronous/asynchronous Cronyx-Sigma WAN adapters

SYNOPSIS    [Toc]    [Back]

     device cx

     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    [Toc]    [Back]

     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
     resources manualy.

     Refere to sconfig(8) for information about the cx adapter configuration.

HISTORY    [Toc]    [Back]

     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     of FreeBSD the cx driver is out of date.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
