Free email and telephone support is provided to application developers using the APIs.

Sockets API - X.25, XOT and ISO Transport - available on: Linux and Windows

The Sockets API is extremely popular as a simple, powerful, easy to use API to access TCP/IP communications networks. The Sockets support for the FarSync X.25 and XOT products retains this ease of use and also allows the special features of X.25 and ISO Transport classes 0 to 3 to be accessed. Documentation and a wide variety of sample applications are provided. Applications using the .NET framework can use the Sockets interface. Further details on the Sockets API

Java API - X.25 and XOT - available on: Linux and Windows

The Java API allows applications written in Core Java Software (J2SE) and Enterprise Java Software (J2EE) easy access to the functions and features of X.25 and XOT offered by the FarSync X.25 adapters. Full documentation and sample applications are provided.

COM Port API - available on: Windows

This interface provides a very quick and easy to use interface to X.25. Each X.25 session is represented by a COM Port controlled by AT commands. The COM Port API is particularly suitable for applications developed in Visual Basic and similar languages or for those not familiar with X.25. Full documentation and a sample application is provided.

HDLC API - LAPB - available on: Windows

Easy to use API to access Lapb layer 2 (HDLC). This interface allows X.25 layer 3 to be completely bypassed. An example application in C is provided.

NCB API - available on: Linux and Windows

A legacy API for the FarSync X.25 products providing compatibility with older version of the products only.

 

FarSync XOT Extension for Linux and XOT Runtime

The XOT extension allows applications using the same API to transmit data over XOT (X.25 over TCP/IP). TCP/IP is normally routed over Ethernet on PCs and Servers. The XOT support is compatible with FarSite's FarLinX X25 Gateway and also other manufactures XOT products. The XOT and X.25 interfaces can be used simultaneously.

The FarSync XOT Extension for Linux is available under product code FS9508, it should be ordered at the same time that the FarSync X25 adapter is purchased, although a retrofit is possible.

FarSync XOT Runtime software is also available that allows XOT to run over the PCs standard TCP/IP connection.

TCP/IP over X.25

The IP over X25 support supplied on the CD-ROM as part of the standard product enables Linux, Windows XP, 2000, Server 2003 and Vista PCs to run the IP protocol over an X.25 network.
