Multi-Teletype Handler Task

This document provides the functional specification for the multi-teletype handler task under the RSX-11 operating system. It details the handler's interface with both the system and the user, including supported hardware teletype devices (KSR33, KSR35, LA32, VT05), I/O function codes for standard operations (READ, WRITE, ATTACH, DETACH), and spooler interface details. Furthermore, it outlines interrupt service routine conventions, including special characters and status word definitions for teletype device control.
