DN8x-Series Remote Station Macros Sep80

This manual, published in September 1980 by Digital Equipment Corporation (DEC), describes the DN8x-series remote station macros. This is an optional software feature designed for customers who wish to modify and extend their DN8x system software.

The macros provide a programmatic interface for user-developed tasks to add specialized functions such as polled terminal handling, screen formatting, data field checking, and input consolidation. The document details programming conventions and describes macro calls for essential system functions, including:

• Task control: Defining, starting, and ending tasks.
• Core (memory) management: Allocating and deallocating buffer areas.
• Task scheduling: Suspending, resuming, and managing task execution priority.
• Intertask communication: Sending and receiving messages via queues.
• Clock reference: Obtaining system uptime.
• Terminal I/O: Reserving terminals, sending/receiving single characters and strings.
• DM11-BB interface control: Manipulating status bits for modem control.

The manual is intended for developers working within the TOPS-10 monitor environment.
