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.

Product Summary

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.

XOT explainer

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.
