G&R

Scope of the product

G&R/Gline comprises a set of communications line handlers with a standard

interface used by the G&R Host Links product set. The Gline line handlers

standardize handling of any kind of communications line. This reduces

application complexity, and makes applications portable across network

environments. Applications are written using one of the communications

libraries supporting the standard communications interface, GlAPI (Gline

Application Programming Interface). The interface works with any Gline line

handler, and can be used to program applications for communication over any

network connection for which there is a Gline line handler, including:

Asynchronous

direct or modem connected

X.25

raw or PAD

TCP/IP

dial-up, ISDN, leased line, raw, Telnet, TNVIP TN5250

and TN3270

DSA/OSI

native Bull DSA and DSA/ISO Work Station over OSI-

transport

DSA/RFC1006

native Bull DSA session over TCP/IP transport

GlAPI is available on all the supported platforms: UNIX/Linux and Windows

servers and workstations.

The G&R Host Links product set uses the native mode Gline API for all

communications.

Third party software houses and customers also use GlAPI when developing

communications applications. GlAPI includes CPI-C for use in applications fol-

lowing the X/Open standard for programmatic access to communications. For

details of the various APIs please refer to the GlAPI Application Programming

Interfaces manual.
