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 Mini Gateway for X.25 and also other manufacturers XOT products. The XOT and X.25 interfaces can be used simultaneously.
The FarSync XOT Extension should be ordered at the same time that the FarSync X25 card is purchased, although a retrofit is possible.
