HPFOPEN call used to open the
file. It can be used to access that
file until the file is closed.
file specification The name and
location of a file. The full
specification for a file includes the
file name, group, and account.
file system The part of the
operating system that handles
access to input/output devices
(including those connected
through the DTC), data blocking,
buffering, data transfers, and
deblocking.
Flash EEPROM See EEPROM.
flow control A means of
regulating the rate at which data
transfer takes place between
devices to protect against data
overruns.
flow control negotiation One
of the network subscribed
facilities selected at subscription
time. This facility allows the Flow
Control parameter to be
negotiated at call set-up time, as
opposed to having a predefined
value.
formal file designator A name

programmatically or in a file
equation to refer to a file.
FOS Fundamental Operating

gateway A node that connects
two dissimilar network
architectures. A gateway can be
either a single node (full gateway)
or two gateway halves.
gateway half A node that works
in conjunction with another node
on another network to form an
internetwork. The only protocol
used by gateway halves is the NS
Point-to-Point 3000/iX Link. See
also full gateway.
gateway half link A link
between the two nodes of a
gateway-half pair. Each of the two
nodes of a gateway-half pair has a
configured link (hardware
interface card) that is used for the
gateway half network interface.
The NS Point-to-Point 3000/iX
Link is the only link that can be
used as a gateway-half link.
gateway half pair A set of two
nodes that are joined by a
gateway-half link. Each node in
the pair must have a
gateway-half network interface
configured, using the link.
Guided Configuration A
method of configuring a node in
which a subset of the complete
