ENet for C# wraps the C-language ENet networking library. For games and other realtime applications, if you use TCP, old data can hold up newer data, even if it is no longer relevant (old positions, etc.). Your players will perceive any lost packet as a "lag burst". ENet supports multiple in-order streams of data, and allows you to decide on reliability on a per-packet basis. The library is useful for both client-server and peer-to-peer architectures.
libnetfilter_cttimeout is an interface to Netfilter Connection Tracking timeouts. It provides a userspace library which provides a programming interface to the fine-grained connection tracking timeout infrastructure. With this library, you can create, update, and delete timeout policies which can be attached to traffic flows.
libmnl is a minimalistic user-space library for Netlink developers. There are a lot of common tasks involved in parsing, validating, and constructing both the Netlink header and TLVs that are repetitive and easy to get wrong. This library aims to provide simple helpers that allow you to re-use code and avoid re-inventing the wheel.
MinimalModbus is an easy-to-use Python module for talking to instruments (slaves) from a computer (master) using the Modbus protocol. Example code includes drivers for Eurotherm and Omega process controllers. The only dependency is the pySerial module. This software supports the ‘Modbus RTU’ serial communication version of the protocol, and is intended for use on Linux, OS X, and Windows platforms. It has been tested with Python2.6, Python2.7, and Python3.2.
PyMQI is a Python library for working with WebSphere MQ (formerly known as MQSeries) implementing MQI and PCF protocols. It allows one to connect to queues, put, browse, get messages, and to programmatically administer MQ objects. PyMQI has been used in production environments for several years and is known to work on Linux, Windows, Solaris, AIX, and HP-UX with queue managers running on Linux, Windows, Solarix, AIX, HP-UX, and z/OS mainframe.
OpenCAN is a software platform for interacting with various Controller Area Network (CAN or CANbus) devices. It provides an abstract C++ interface that can be used to control CAN devices. Support for specific devices can be written as plugins, and then loaded through a simple API call. Each component is cross-platform, enabling the efficient development of CAN software on Windows, Linux, and Mac OS X.
