DL11 Asynchronous Line Interface Manual

The DL11 Asynchronous Line Interface is a character-buffered communications interface designed for the PDP-11 Unibus. This manual covers the five available options (DL11-A through DL11-E), detailing their operational differences, data formats, register assignments, and interrupt control logic. It provides comprehensive sections on installation, configuration (including jumper and switch settings for baud rate selection), and programming information, with examples of device register manipulation and dataset interface handshaking.
