NAME
       ci - Interphase 5515 ATM Classical IP STREAMS Driver

SYNOPSIS
       /dev/ci

DESCRIPTION
       The ci is a STREAMS driver that works in conjunction with the ia
       Interphase 5515 ATM device driver to provide Classical IP support as
       specified in RFC-1577.  The ci driver is a STREAMS multiplexer
       providing DLPI style 2 support.  The ci driver provides the
       appearance of connectionless service.  Multicast and broadcast
       operations are not supported by this type of connection service.  ci
       is ILINKED over the ia Interphase 5515 ATM STREAMS device driver by
       the ipatmsetup utility.

       In order to use the Classical IP STREAMS driver both ci and ia must
       be configured into your system.  ci is configured into your system by
       adding ci() to the DG/UX system configuration file.  (See the ia(7)
       man page for details on how to configure ia into your system.)  After
       ia and ci are configured into your system, you must specify the
       Classical IP interface in the /etc/tcpip.params file. This is done by
       specifying the interface to be ciN where N is the PPA (Physical Point
       of Attachment) used by atmbind and is also used in specifying which
       atmconf file is to be used by ipatmconfig.  (See atmbind(1m) and
       ipatmconfig(1m) for more details.)  Classical IP requires the
       signalling deamon signald to be running in order to function
       properly.

EXAMPLE
       The following is an example of specifying the interface host-classip
       will be a Classical IP type connection for PPA 0.

       HOSTNAME=host-classip DEVICE=ci0 NETMASK=0xffffff00

NOTES
       The ci driver cannot function alone.  It requires services provided
       by ia(7).
