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. (For DTC 72MX and DTC 16TN only.)
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 Manager/UX 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.
I
ICMP Internet control message protocol. An integral part of the Internet protocol that
handles error and control messages. Gateways and hosts use ICMP to send reports
of problems about datagrams back to the original source that sent the datagram.
ICMP also includes an echo request/reply used to test whether a destination can be
reached and will respond.
IEEE 802.3 A standard for a broadcast local area network published by the Institute for
Electrical and Electronics Engineers (IEEE). This standard is used for both the
ThinLAN and ThickLAN implementations of the LAN.
initialization string A sequence of control characters used to initialize a terminal, printer, or plotter
when a connection is established from a host on the network.
Internet Protocol
(IP) A protocol used to provide routing between different local networks in an
internetwork, as well as among nodes in the same local network. The Internet
Protocol corresponds to layer 3, the Network Layer, of the OSI model. See also IP
address.
