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.
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.
- Three new modem types for attached device: US modem In Out, European
modem In Out, and Five wires modem.
- Two new data length/parity settings.
- Configuration to enable or disable flow control between the DTC and the
attached device.
- Configuration of the number of stop bits on Host-Based DTC ports.
- "Keep Alive" mechanism can be activated.
- Port configuration parameters (data length and parity) can be specified
as forced when binary mode is selected.
- Dynamic Configuration of new port configuration parameters.

10, "Technical Articles," and to the manual, Configuring System for
Terminals, Printers, and Other Serial Devices.
