About The SNADIS Guide

This guide is intended for OEMs and adapter vendors who are developing their own SNALink software to work with Microsoft® SNA Server. Before using it you should be familiar with SNA Server concepts. It provides the following information:

Internal concepts of SNA Server that are required to integrate new communications adapters into the server environment.
Definitions of the interfaces used by SNA Server to communicate with SNALinks.
Information on using SNA Server's configuration and diagnostics features.
Instructions for compiling and linking the SNALink support software.

This guide covers the following topics:

SNA Server Concepts: Introduces the key concepts used in SNA Server that you need to consider when integrating new communications adapters.
The SNALink Interface: Explains scheduling within an SNA Server SNALink, the interface that SNALinks use to communicate with the Base, and the entry points available.
The Data Link Control Interface: Explains the messages and message sequences used for communications between an SNALink and the local 2.1 node.
Message Formats: Describes the SNA Device Interface Specification (SNADIS) interface in terms of message formats.
SNALink Configuration Information: Describes the mechanism used by SNALinks to gain access to SNA Server configuration information and explains how to interpret and use this information.
Setup Information: Describes the mechanism provided to allow IHV setup utilities to configure SNA Server SNALinks.
Diagnostics: Describes the interfaces to the SNA Server message logging and tracing facilities and explains how SNALinks can use them.
Compiling and Linking with SNA Server: Explains how to include the required SNA Server header files and libraries when compiling and linking your SNALink and provides information on compiler flags to be used.
Synchronous Dumb Card Interface: Provides details of the interface used by the SNA Server synchronous dumb card device driver.
SNA Modem Status Interface: Discusses the interface between the modem status and the SNALink.
SNA Performance Monitor Interface: Describes the interface for performance monitoring used by the SNA Server-supplied SNADIS links.
