NAME
       pefn - Peregrine FDDI network interface

SYNOPSIS
       pefn ([def]) or
       pefn @devicecode (VMEA16addr)

DESCRIPTION
       The pefn device driver allows an AViiON system that includes a V/FDDI
       controller to access a Fiber Distributed Data Interface (FDDI)
       network. To set up this interface, you enter one or more pefn
       statements in the DG/UX system configuration file.

       The pefn statement has two formats (shown above and illustrated
       below). The first format accepts all defaults for a specified
       controller board.  The second format specifies all values:

       def            A number from 0 to 7, or null for 0, identifying the
                      controller board defaults to use

       @devicecode   The network controller device code, preceded by the @
                      character

       VMEA16addr   The VME A16 (short I/O) address of the controller

       The pefn device is implemented as a clonable Streams driver.  This
       means that you can open a single node, such as /dev/pefn0, to access
       any unused minor device.  Each subsequent access of the node via the
       open(2) system call allocates a separate Stream (minor number) to the
       device driver.

DIAGNOSTICS
       Use the -i option with netstat(1C).

EXAMPLES
       The following entries in a DG/UX configuration file configure two
       FDDI controllers with default values, at nodes /dev/pefn0 and
       /dev/pefn1:

            pefn(0)
            pefn(1)

       Note that either pefn() or pefn(0) will create the initial node.

       The following statement configures an FDDI controller with device
       code 7B and VME A16 address ffff2400:

            pefn@7B(ffff2400)
