NS 3000/iX is the name of Hewlett-Packard's
interactive and programmatic user-level, network services. All of
these services are listed below and are fully documented in this
manual:
Virtual Terminal (VT)
creates an interactive session for you on another system in the
network, making your terminal appear as though it were directly
connected to the other system. This service permits you to issue
commands to the remote operating system, use subsystems such as
editors and compilers within the remote environment, and run application
programs that reside on the remote system. A feature called Reverse
Virtual Terminal enables a local application program to communicate
efficiently with remote terminals.
Remote File Access (RFA)
enables you to perform I/O operations to files and peripheral devices
located on other nodes.
Remote Data Base Access (RDBA)
allows you to access and update TurboIMAGE data bases located on
other nodes. TurboIMAGE is a Hewlett-Packard data base management
system.
Network File Transfer (NFT)
allows you to transfer or copy files from one node to another, or
within a single node, interactively or programmatically. For information
on transfers between the PC and the HP 3000, refer to the
User Guide for HP PC Network Services.
Remote Process Management (RPM)
enables a given process to create and terminate processes on other
nodes. RPM is commonly used in conjunction with Network Interprocess
Communication (NetIPC). NetIPC provides programmatic access to the
Transmission Control Protocol (TCP), which is the Transport Layer
protocol used by NS 3000/iX link products. For more information
on NetIPC, refer to the NetIPC 3000/iX Programmer's Reference
Manual.
These network services allow you to perform essential functions
across a network or across gateways in an internetwork. In addition
to a "virtual terminal" you have what amounts
to virtual storage and virtual devices; you are not limited to the
processing and storage capacities of your own system.
The NS 3000/iX network services including NFT (DSCOPY)
and RFA do not support POSIX—the services cannot work with
either bytestream files or files residing in HFS (hierarchical file
system) directories. To transfer bytestream files across systems,
use Hewlett-Packard's FTP/iX product.
