Introduction to DTC Manager/UX
This chapter describes the DTC Manager/UX software and the types of DTCs it can
manage.
The DTC Manager/UX software provides management functions for Data
Communications Terminal Controllers (DTCs) that enable you to create and
maintain DTC configuration files. The DTC Manager/UX runs on the HP 9000
Series 700
1
and 800 computer systems.
The HP 9000 system is called the host system. DTC Manager/UX manages DTCs
that are directly connected to the host system or connected to other HP 9000 systems
on the same LAN.
Note Other HP software products are available for managing DTCs from a PC or from an
HP 3000 system.
DTC overview
The HP Data communications and Terminal Controller (DTC) is a versatile
communications server for connecting systems to terminals, printers, and other
asynchronous devices. The types of connections available through a DTC are
determined by the connector cards or boards mounted in and configured for that
DTC.
A DTC controls the transfer of data between the devices connected to it and the
computer systems which those devices can access. The DTC controls
communications that would otherwise need to be controlled by the computer
system. Therefore, the DTC frees system resources and can improve the processing
performance of the Hewlett-Packard computers that use the DTC as their
communications controller.
