Part of the
X.PORT
Product Range


Application Development

For application developers the X.PORT products have a very flexible API which permits access to the low level features of X.25, ISO Transport and a Triple-X Pad whilst permitting fast development when requirements are more straightforward. A working documented sample C source program interfacing to X.25 is included as part of the software package. The source code access routines can be directly included in your application to fast track your development. There is comprehensive on-line API documentation (Adobe PDF format) with helpful advice on the best way to use the API. The developers kit is supplied free on the CD with every product.

The API is shared with the FarSync PCI product range, this means that Windows NT applications developed to use the X.PORT X.25 API will work with FarSync without change. It most cases applications developed to use FarSync will also work with X.PORT.

IP over X.25

The IP/X25 module enables PCs to run the IP protocol over an X.25 network. All higher level protocols that run over IP including TCP, UDP, HTTP and FTP are handled. The module complies with RFC 1356 to permit interoperation with other X.25 attached devices.

Easy Line Configuration

The Version 2.0 X.PORT product is simple to install on Windows NT, configuration is by a user friendly application designed to make X.25 configuration easy, click for example, there's context sensitive help and an on-line manual should it be required. Many of the parameters such as DTE / DCE selection are determined automatically, selecting the line speed by default automatically sets suitable timer and retry values. The advanced tab permits users to exactly specify the configuration of the line where this is required, click for example.

Line Monitor

Two line analysis utilities are included. X25STATS keeps statistics on the health of the line, these include: user data, packet and frame type counts and the connection status. X25MON displays in real time the packet and frame level decodes of data transmitted and received.
