     cp — driver for synchronous Cronyx Tau-PCI WAN adapters


     To compile this driver into the kernel, place the following line in your kernel
     configuration file:

           device cp

     Alternatively, to load the driver as a module at boot time, place the following line in


     Additional options:
     device sppp
     options NETGRAPH
     options NETGRAPH_CRONYX


     The cp 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 cp
     driver will be compiled with netgraph(4) support.  Otherwise, it will be compiled with
     sppp(4) support.

     Refer to sconfig(8) for information about the cp adapter configuration.


     The cp driver supports the following models of Tau-PCI WAN adapters:

     Cronyx Tau-PCI        V.35 and RS-232 interfaces
     Cronyx Tau-PCI/R      RS-530(RS-449) and X.21 interfaces
     Cronyx Tau-PCI-L      one V.35 and RS-232 interface, low profile
     Cronyx Tau-PCI-L/R    one RS-530(RS-449) and X.21 interface, low profile
     Cronyx Tau-PCI-E1     fractional E1 interfaces
     Cronyx Tau-PCI-G703   unframed E1 interfaces
     Cronyx Tau-PCI-2E1    fractional E1 and unframed E1 interfaces
     Cronyx Tau-PCI-4E1    fractional E1 and unframed E1 interfaces
     Cronyx Tau-PCI-E3     E3 interface
     Cronyx Tau-PCI-T3     T3 interface
     Cronyx Tau-PCI-STS1   STS-1 interface


     ctau(4), cx(4), sppp(4), ifconfig(8), sconfig(8), spppcontrol(8)


     The cp driver was added in FreeBSD 5.3 and FreeBSD 4.11.  The cp driver for previous
     versions of FreeBSD is available from
