DTS/TIO Subsystem

by Wendy Cheng

Commercial Systems Division

Overview

The Datacommunications and Terminal Subsystem (DTS) consists of

host (HP 3000) based software and the DTC (Datacommunications and

Terminal Controller) terminal server.

The DTC family of products supports X.25 communication and Telnet

access to HP 3000 systems, and TCP/IP communication to HP 9000 and

non-HP systems.

The DTS allows terminal, PCs in terminal emulation mode, serial

printer, and other asynchronous devices to communicate with

LAN-based hosts in HP-only and multivendor networking

environments.

MPE/iX 6.0 release:
