The FarSync XOT Runtime software provides an API to support applications that previously required an X.25 interface to use XOT instead.
FarSync XOT Runtime has been developed to provide high performance and very reliable XOT connectivity for Windows. FarSync XOT Runtime for Windows inter-operates with the FarLinX X25 Gateway , FarSync XOT Runtime for Linux and other third party XOT devices, which can allow a complete X.25 network to be replaced by TCP/IP, eliminating hardware and costs just leaving a short X.25 connection to the host. The diagram above illustrates this.
A comprehensive Developers Toolkit is included with the product.
The API is based on Sockets (compliant with Winsock2) and is compatible with the Microsoft defined X.25
Sockets API. Applications written to use the Microsoft X.25 Sockets API, FarSync X.25 cards and some other commonly used X.25 cards will work with the FarSync XOT product without change.
The API supports standard AF_ISO / ISOPROTO_X25 sockets used by a number of applications, such as
MS-Exchange. It also supports the AF_X25 address family used by the applications written to use FarSync
Applications developed in most programming languages, including Visual Basic, Delphi, C++ and .NET
applications, can use the Sockets API to FarSync XOT, and there is a Java Extension API supplied to provide
access from Java applications.
Both X.25 SVCs and PVCs are supported with a maximum of 4096 simultaneous connections.
FarSync XOT Runtime is supported on Windows 10, 8, 7, Vista, Server 2003 and Server 2008. Multi-processor,
32 and 64 bit systems are supported. For 64-bit applications support is planned for a future release.

The FarSync XOT Runtime is suitable for connection to remote systems running XOT, typical applications include:
- XOT replacements for X.25 networks
- E-Commerce gateways for credit verification
The Developers Toolkit is included free with the FarSync XOT Runtime product it features:
- Documented working C and Java source sample programs. Source code from these samples can be used to fast-track your development process.
- Comprehensive API manuals with function call definitions and helpful advice on the best way to utilise the various interfaces.
- Free email and telephone assistance by the FarSite Engineers group to application developers.
APIs for Application Development
For application developers needing to access XOT there is a choice of a Sockets API or a Java API. Both APIs interfaces may be used simultaneously by different programs if required.
The WinSock2 compliant sockets interface provides a programming language independent high level
connection orientated interface with access to a comprehensive set of XOT / X.25 features. The API is compatible with the Sockets API for the FarSync X25 cards and the Microsoft X.25 Sockets API standard. Address families AF_ISO / ISOPROTO_X25 and AF_X25 are supported. XOT-specific additions to the API provide access to XOT parameters such as the IP address for the remote XOT node.
The Java API for FarSync X.25 is supported on XOT and allows applications written in Core Java Software
(J2SE) and Enterprise Java Software (J2EE) easy access to the functions and features of FarSync XOT.
Further details on the XOT/X.25 Developers Toolkit and APIs.
The FarSync XOT Software is simple to install and use immediately. Configuration is required to map the X.25
Destination Address to the IP Address of the remote host or node, except when the application is able to supply such information itself via the XOT-specific features of the API.
There is a text file mapping from X.25 parameters to IP Addresses.
The widely used line monitoring utility Wireshark can be used to monitor and decode the FarSync XOT sessions providing a comprehensive analysis of line traffic required by developers and systems installers.
The XOT software and the Developers Toolkit are all included on the CD-ROM. New versions of the XOT software are made available for downloading from the Download page as they are released.
