.Sh NAME
.Nm cp
.Nd driver for synchronous Cronyx Tau-PCI WAN adapters
.Sh SYNOPSIS
.Cd "device cp"
.Pp
Additional options:
.Cd "device sppp"
.Cd "options NETGRAPH"
.Cd "options NETGRAPH_CRONYX"
.Sh DESCRIPTION
The
.Nm
driver needs either
.Xr sppp 4
or
.Xr netgraph 4 .
Which one to use is determined by the
.Dv 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.
.Pp
Refer to
.Xr sconfig 8
for information about the
.Nm
adapter configuration.
.Sh HARDWARE
The
.Nm
driver supports the following models of Tau-PCI WAN adapters:
