This chapter describes the use of LAN drivers that support
the LAN devices listed in the Software Product Description for the
OpenVMS Operating System (SPD 82.35.xx). Most of the LAN devices
are described here, but refer to the Software Product Description
for the OpenVMS Operating System for the definitive list of supported
devices.
The LAN drivers support two user interfaces or APIs, QIO and
VCI (VMS Communications Interface). This chapter describes the
QIO interface to the LAN drivers, primarily. But most of the QIO
functionality applies to the VCI interface as well. And the description
of the other features and characteristics of the LAN devices and
LAN drivers applies equally to either interface.
The LAN drivers are composed of a set of LAN common routines
that implement the user interfaces plus a LAN port driver for each
different type of LAN device. The LAN drivers comprise the Data
Link layer as defined by the OSI Model defined in
Local Area Network (LAN) Terminology.
