Eltima Serial Port Driver software product simple to Virtual serial ports for virtual construction. Null modem serial ports by ports will have two-way communication. All information is recorded on one side of the connection is visible on the other side. Com or serial ports built in this software is exactly the same as real serial ports and no functional difference with them. All ports such as port settings can really do. Using Virtual Serial Port Driver without worrying about messy hardware can Dvrbrtan extremely define com port. Ports created by the program with its emulator driver and all standard hardware signal lines support (DTR / DSR, RTS / CTS, RING, ERROR, DCD, etc.

A filter driver library that allows you to track and control filesystem, registry, and process manager operations. CBFS Filter allows you to intercept and react to filesystem, registry, and process manager operations as they occur. Advanced filter rules ensure that your application only gets notified of the operations that you actually care about, and intelligent access rules enable you to enforce access restrictions with no additional effort. Without writing a single line of driver code, you'll be able to modify data, encrypt files on-the-fly, control access, and block requests entirely.

A powerful library that allows you to create and manage virtual filesystems in your Windows applications. CBFS Connect allows you to present any data source as a fully-featured Windows filesystem—be it database records, local or remote files, dynamically-generated content, or anything in-between. Without writing a single line of driver code, you'll be able to expose your data as just another drive full of files and folders, making it easy for users to view and interact with, and giving other applications the ability to access and manipulate it via standard file APIs.

LINQPad is not just for LINQ queries, but any C#/F#/VB expression, statement block or program. Put an end to those hundreds of Visual Studio Console projects cluttering your source folder and join the revolution of LINQPad scripters and incremental developers. Reference your own assemblies and NuGet packages. Prototype your ideas in LINQPad and then paste working code into Visual Studio. Or call your scripts directly from the command-line. Experience LINQPads rich output formatting, optional debugger and autocompletion, and the magic of dynamic development and instant feedback!

A library for creating and managing virtual disk drives backed by standalone datastores. CBFS Disk allows you to create virtual disk drives formatted as FAT, NTFS, or any other filesystem with just a few lines of code. The contents of each virtual disk drive are stored in a single contiguous block of data, managed by the CBFS Disk system driver itself. All your application has to do is decide where to store it, and then handle read and write requests performed on it. It's that easy.

ZylSerialPort.NET is a thread based, event driven, asynchronous / synchronous serial port .NET framework / component.
Use ZylSerialPort.NET component to easily communicate with external devices on serial port connection, such as modems, bar code readers, GSM modules and others.

ZylGpsReceiver.NET is an event driven .NET framework / component collection that communicates with a GPS receiver. It returns latitude, longitude, altitude, speed, course, heading and many other useful parameters of the current position and the parameters of the satellites in view. The component is extended to calculate distances and make conversions between different measurement units and there is also an extension for google maps support, to be able to visualize the GPS positions in real time on a map engine.
