DECnet-DOS Programmer's Reference Manual

This document is a programmer's reference manual for DECnet-DOS Version 1.1, which enables IBM PC/XT/AT and Rainbow 100 computer systems to function as end nodes on a DECnet network. It provides guidance on creating applications that utilize task-to-task communication (via sockets or standard MS-DOS I/O) and transparent file access. The manual is organized into 6 chapters covering network programming concepts, transparent file access, transparent task-to-task communication, C language socket interface calls, DECnet utility functions, and assembly language network process interface calls, supplemented by 8 appendices detailing definitions, data structures, and error codes.
