DSV11 Synchronous Device Driver Manual

This document is the DSV11 Synchronous Device Driver Manual (Order No. AA-JG79B-TE), published by Digital Equipment Corporation in April 1988.

It serves as a comprehensive guide for installing and controlling the DSV11 Synchronous Device Driver (V1.0) on VAX/VMS V4.7 systems.

The manual details:

• The DSV11 device itself, a Direct Memory Access (DMA) communications adapter for MicroVAX II (Q22-bus) processors, supporting DDCMP, HDLC (LAPB/LAPBE), SDLC, and BISYNC protocols.
• Installation procedures for the DSV11 driver, including system requirements and an example installation log.
• How to control the DSV11 driver through the VAX/VMS operating system using SQIO system services, covering I/O operations (Read, Write), setting modes and characteristics, sense mode operations, and modem control.
• Methods for obtaining DSV11 device and driver information, including characteristics, status, and error summaries.
• Guidance on tuning the system for optimal performance, particularly regarding dynamic memory allocation.
• An example program demonstrating typical DSV11 driver operations.

The manual is intended for users installing the DSV11 driver and system programmers (with assembly language experience) who wish to interact with the driver directly.
