 17.Dt CX 4 i386
 18.Os
 19.Sh NAME
 20.Nm cx
 21.Nd "driver for synchronous/asynchronous Cronyx Sigma WAN adapters"
 22.Sh SYNOPSIS
 23To compile this driver into the kernel,
 24place the following line in your
 25kernel configuration file:
 26.Bd -ragged -offset indent
 27.Cd "device cx"
 28.Ed
 29.Pp
 30Alternatively, to load the driver as a
 31module at boot time, place the following line in
 32.Xr loader.conf 5 :
 33.Bd -literal -offset indent
 34if_cx_load="YES"
 35.Ed
 36.Pp
 37Additional options:
 38.Cd "device sppp"
 39.Cd "options NETGRAPH"
 40.Cd "options NETGRAPH_CRONYX"
 41.Pp
 42In
 43.Pa /boot/device.hints :
 44.Cd hint.cx.0.at="isa"
 45.Cd hint.cx.0.port="0x240"
 46.Cd hint.cx.0.irq="15"
 47.Cd hint.cx.0.drq="7"
 48.Sh DESCRIPTION
 49The
 50.Nm
 51driver needs either
 52.Xr sppp 4
 53or
 54.Xr netgraph 4 .
 55Which one to use is determined by the
 56.Dv NETGRAPH_CRONYX
 57option.
 58If this option is present in your kernel configuration file, the
 59.Nm
 60driver will be compiled with
 61.Xr netgraph 4
 62support.
 63Otherwise, it will be compiled with
 64.Xr sppp 4
 65support.
 66.Pp
 67The base I/O port address specified in
 68.Pa /boot/device.hints
 69must match the port address set by the jumpers on the board.
 70The DMA I/O channel and interrupt request numbers are configured
 71by software at adapter initialization.
 72Legal values are:
 73.Pp
 74.Bl -tag -compact -width Port:
 75.It Port :
 760x240, 0x260, 0x280, 0x300, 0x320, 0x380
 77.It IRQ :
 783, 5, 7, 10, 11, 12, 15
 79.It DMA :
 805, 6, 7
 81.El
 82.Pp
 83The
 84.Nm
 85driver supports autodetection.
 86As for all non-PNP hardware, using
 87autodetection could lead to some potential problems with other devices during
 88the hardware detection process.
 89It is always better to specify hardware resources manually.
 90.Pp
 91Refer to
 92.Xr sconfig 8
 93for information about the
 94.Nm
 95adapter configuration.
 96.Sh HARDWARE
 97The
 98.Nm
 99driver supports the following cards:

122.Sh HISTORY
123The
124.Nm
125driver was updated in
126.Fx 5.2
127and
128.Fx 4.10 .
129In most of the previous versions of
130.Fx
131the
132.Nm
133driver is out of date.
134The
135.Nm
136driver for previous versions of
137.Fx
138is available from
139.Pa http://www.cronyx.ru/ .
