SPD 26.70.11

for OpenVMS, Version 1.6

 

This SPD describes HP SNA Printer Emulator for Open- VMS, which is available for the OpenVMS I64, Open- VMS Alpha and OpenVMS VAX platforms. All information applies to all platforms unless otherwise indicated.

DESCRIPTION

HP SNA Printer Emulator for OpenVMS (PrE) is an OpenVMS layered software product that allows suitably configured OpenVMS systems to receive printable data from IBM host-based applications. These applications will originally have been developed to produce output for an IBM 3287 printer in system mode that is connected to an IBM 3274 cluster controller in a Systems Network Architecture (SNA) networking environment. Access from the IBM system to OpenVMS systems is via one of the following SNA servers or gateways:

TCP/IP or DECnet Connections

HP SNA Peer Server

HP SNA Domain Gateway

HP SNA Access Server for Windows NT®

HP SNA Server for OpenVMS Alpha, a layered prod- uct that supports local access as well as TCP/IP and DECnet clients

DECnet Only Connections

HP DECnet SNA Gateway for Synchronous Trans- port

HP DECnet SNA Gateway for Channel Transport

HP SNA Server for OpenVMS VAX, an OpenVMS VAX layered product that supports local access as well as remote DECnet clients

In an actual IBM 3287 environment, data transfer is one way (from host to printer) and generates hard copy. The PrE Access software will allow OpenVMS users to direct the received output either to be printed via the Open- VMS Print Symbiont or spooled to a disk file.
