.Dd November 27, 2003 .Dt CX 4 i386 .Os .Sh NAME .Nm cx .Nd driver for synchronous/asynchronous Cronyx-Sigma WAN adapters .Sh SYNOPSIS .Cd "device cx"
p Additional options: .Cd "device sppp" .Cd "options NETGRAPH" .Cd "options NETGRAPH_CRONYX"
p In
a /boot/device.hints : .Cd hint.cx.0.at="isa" .Cd hint.cx.0.port="0x240" .Cd hint.cx.0.irq="15" .Cd hint.cx.0.drq="7" .Sh DESCRIPTION The .Nm driver needs either .Xr sppp 4 or .Xr netgraph 4 . Which one to use is determined by the NETGRAPH_CRONYX option. If this option is present in your kernel configuration file, the .Nm driver will be compiled with .Xr netgraph 4 support. Otherwise, it will be compiled with .Xr sppp 4 support.
p The base I/O port address specified in
a /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:
p l -tag -compact -width Port: t Port : 0x240, 0x260, 0x280, 0x300, 0x320, 0x380 t IRQ : 3, 5, 7, 10, 11, 12, 15 t DMA : 5, 6, 7 .El
p The .Nm 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.
p Refer to .Xr sconfig 8 for information about the .Nm adapter configuration. .Sh SEE ALSO .Xr sppp 4 , .Xr ifconfig 8 , .Xr sconfig 8 , .Xr spppcontrol 8 .Sh HISTORY The .Nm driver was updated in .Fx 5.2 . In most of the previous versions of .Fx the .Nm driver is out of date. The .Nm driver for previous versions of .Fx is available from
