New Features for DTS/TIO Subsystem

Introduction
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.
New Features
The DTS/TIO subsystem provides the following new functionality for
MPE/iX 6.0 release:
• Support of 400 DTCs.
• Support of 2000 device classes
• Configuration of the maximum number of sessions for a terminal
switching port on the Host-based DTC management.
• Configuration of the number of hosts sharing the printer for a
printer switching port on the Host-based DTC management.
The following enhancements were made to MPE/iX release 6.0 for the
DTS/TIO subsystem to provide support for all DTC port configuration
parameters of DTC version 14.4 for Host-based DTC management.
Prior to release 6.0, these features were only available on the OpenView
DTC Manager in a PC-based management configuration.
These new features are as follows:
• Three new modem types for attached device. The new modem types
are US modem In Out, European modem In Out, and Five wires
modem.
• Two new data length/parity settings. The DTS/TIO software has
been enhanced to support two new parity types. The two new parity
types are 8 bits data length with even parity and 8 bits data length
with odd parity.
