FarSync XOT Runtime
The FarSync XOT Runtime software provides an API to support applications that previously required an X.25 interface to instead use XOT (X.25 over TCP/IP) as the communications method for PCs and Servers running Linux and Windows.
FarSync XOT Runtime has been developed to provide high performance and very reliable XOT connectivity for Linux and Windows. FarSync XOT Runtime inter-operates with the FarLinX Mini Gateway’s XOT support and other third party XOT devices, which can allow a complete X.25 network to be replaced by TCP/IP including IPv6, eliminating hardware and costs just leaving a short X.25 connection to the host. This diagram illustrates this.
There are 2 main APIs, a Sockets based interface and a Java API. There is also an API to the ISO Transport layers (ISO 8073 – connection oriented). A comprehensive Developers Toolkit is included with the product. The API is compatible with the FarSync X.25 APIs.
FarSync XOT Runtime is supported on Linux kernel versions from 2.6.12 onwards, including the leading distributions supplied by Red Hat, CentOS, SuSE, Debian, Ubuntu, Slackware, Fedora and others. Multi-processor, 32 and 64 bit systems are supported. FarSite is committed to supporting the FarSync XOT products on new versions of Linux as they are released. The source code for the driver and the libraries for the API are supplied with the product.
The FarSync XOT Runtime software for Windows provides an API to support applications that previously required an X.25 interface to instead use XOT (X.25 over TCP/IP) as the communications method for PCs, running Windows 10 or 11, or Servers, running Windows Server 2019 or 2022.
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 and 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.
- Source code for the API libraries.
- Line monitoring analyser for the X.25/XOT traffic
- Free email and telephone assistance to application developers.
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. API manuals and many example applications are included in the Developers Toolkit for both types of interface. The APIs are compatible with the APIs for FarSync X.25 cards.
A line monitor utility is included, this can display data sent over the XOT lines at the frame and packet level, it is invaluable when developing and debugging applications. A status utility allows display of the channel connection status and statistics of user data, packet and frame types.
Installation scripts adapt to install the software on the major Linux distributions and a manual install option is available using the scripts as a guide.
Source code is available as a .tar.gz.
The Windows version is supplied as a single, Windows Installer-compatible executable.
A comprehensive configuration guide, commands reference and configuration examples are provided as part of the HTML documentation pack.
Configuration is by a Java and XML-based GUI configuration application. A typical screen is shown below.
Text file based configuration is also available if required.
