Glossary
escape sequence A sequence of characters beginning with the escape character and followed by one or
more other characters, used to convey control directives to printers, plotters, or
terminals. Escape sequences are used when, for example, you need to include special
characters in a screen message, such as a welcome message.
Ethernet A Local Area Network system that uses baseband transmission at 10 Mbps over
coaxial cable and unshielded twisted pair. Ethernet is a trademark of Xerox
Corporation.
extended switching A DTC 16RX configuration that makes use of two asynchronous DTC 16RX ports
on one or two (back-to-back)DTC 16RXs.
F
file system The organization of files and directories on a hard disk.
flow control A means of regulating the rate at which data transfer takes place between devices, to
protect against data overruns.
Flash EEPROM Flash Electrically Erasable Programmable Read-only Memory, the type of ROM
used in the DTC 16RX. Flash EEPROMs can be reprogrammed.
FOS Fundamental operating system (MPE/iX).
front-end DTC A DTC used to implement the gateway part of Routable AFCP. It must be on the
same LAN as the HP 3000 Series 900 host system.
G
gateway A node that connects two dissimilar network architectures, for example, a LAN and
a PSN or two PSNs, and provides protocol translation between them. A gateway can
be either a single node (full gateway) or two gateway halves.
H
handshaking A communications protocol between devices or between a device and the CPU. It
provides a method of determining that each end of a communications link is ready to
transmit or receive data, and that transmission has occurred without error.
hardware handshake Uses modem signals CTS and RTS to pace the data transfer from the DTC to the
attached device.
host-based network management
A method of managing asynchronous communications for HP computers. All of the
control software is configured on a single HP host and is downloaded to the DTCs
that are managed by that host. The DTC 16RX Manger is a host-based management
product.
host computer The primary or controlling computer on a network. The computer on which the
network control software resides. For HP purposes, it can also be used to distinguish
the system (host) from the DTC 16RX.
