DOS/BATCH Device Driver Information

This manual serves as a comprehensive guide for developers and system users on implementing device drivers for the DOS/BATCH operating system on PDP-11 hardware. It covers key technical topics including driver structure, standard interface tables, interrupt servicing, and error handling. Additionally, it details how these drivers can be used in a stand-alone environment outside of the main DOS/BATCH control, providing assembly examples for both position-dependent and position-independent code. The document includes detailed appendices that define the driver structure, monitor communication protocols, and specific routines like OPEN, CLOSE, and TRANSFER, alongside a practical sample listing of the LP11 Line Printer driver.
