NAME

     cp - driver for synchronous Cronyx Tau-PCI WAN adapters

SYNOPSIS

     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 loader.conf(5):

           if_cp_load="YES"

     Additional options:
     device sppp
     options NETGRAPH
     options NETGRAPH_CRONYX

DESCRIPTION

     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.

HARDWARE

     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
