An RFC 6749 OAuth2 Client implemented as a Lazarus Package. The client is intended to be fully featured and supports the following grant types: Authorization Code Grant Implicit Grant Resource Owner Password Credentials Grant Client Credentials Grant. Attention has also been paid to extensibility. The client also provides: A means of implementing an Extension Grant, including new grant types. Support for new token types Support for New Endpoint Parameters, and Support for additional error codes. This OAuth2 Client uses an external User Agent - the System Web Browser - and incorporates in internal http server for handling redirect responses from an Authorization Server. The package uses the Indy Component library for both an http/https client and an http server. When the https protocol is used the OpenSSL library must also be installed and available for use. Multithreading support is required for Authorization Code and Implicit Grants. The package is written in Object Pascal and is made available under the Lesser GPL. The package requires the Indy package for http/https protocol support. It has been configured for use with the MWA Software IndySecOpenSSL package and the Indy Component Library. A separate branch (Indy106Compat) is also available. This will work with the Indy Component library on its own. However, you will be limited to using the unsupported OpenSSL 1.0.2 library (current is OpenSSL 3.x) and TLS 1.2. For installation instructions please refer to the User Guide.

OpenXP 5 is a multi-protocol offline mail and news reader for the text console, supporting internet email, Usenet, Fidonet, ZConnect, etc. It is based on OpenXP (https://sourceforge.net/p/openxp, currently inactive) which is based on CrossPoint (XP) by Peter Mandrella. OpenXP 5 is capable of establishing TLS encrypted connections to POP3, IMAP, SMTP and NNTP based servers and supports the new IPv6 protocol. see: http://de.wikipedia.org/wiki/CrossPoint http://svn.code.sf.net/p/openxp5/code/doc/Crosspoint_Versions.pdf http://groups.google.com/forum/#!forum/de.comm.software.crosspoint
Establishing asynchronous, multithreaded, bidirectional communication without blocking messages can be time consuming and error prone. Using libTML allows you to implement asynchronous message exchange on top of the IETF standard protocol BEEP (Blocks Extensible Exchange Protocol) without the need to fiddle around with the basics of message processing. All your work can be put into the features of the application instead of taming a TCP/IP socket.
MW Media Player is a all-in-one audio video player classic which provides the best possible media experience. MW Media Player its open source multimedia player and the framework is based on mpui mplayer code. The Player runs almost all multimedia files, DVDs, Audio CDs, VCDs, and various streaming protocols,decodes most of codecs (MPEG-2, DivX, H.264, MKV, WebM, WMV, MP3, etc.) so no codec packs are needed. It runs all at glance without the need to install any codec. A simple, fast, and powerful easy to use video player that allows you to create, download or save videos from youtube or any other tube site with the help of an integrated video downloader.
Multi platform toolkit for an interactive DNS shell commands exfiltration, by using DNS-Cat you will be able to execute system commands in shell mode over DNS protocol
This library (the DLL), to work with a multimeter APPA-109N through physical or virtual COM port over USB in OS NT/2000/2003/XP/Vista/7/8, designed for querying, reading and decoding data measurements APPA WinDMM100 protocol 95/98 and sound measurement data. DLL provides universal access for other applications, regardless of the language in the environment Win OS. DLL for use in their projects comply with the agreement on stdcall-calls. Type of calling convention is declared after the function prototype, whether the listing of functional type or function declaration.
SnapModbus is an Open-Source multi-platform suite (library and tools) to manage Modbus communication in strict adherence to the modbus.org specifications, both master and slave side. It supports all the functions described in the documents: * MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1b3 * MODBUS MESSAGING ON TCP/IP IMPLEMENTATION GUIDE V1.0b * MODBUS over Serial Line - Specification and Implementation Guide V1.02 through the standard transport protocols and the most widespread unofficial protocols (UDP, RTU Over TCP, RTU Over UDP) It’s released under lglp v3, so it’s free also for commercial use.

Control MIDI devices with 32/64bit VCL/FMX components for Delphi 10 supporting native Windows and macOS. Support for iOS (Beta) and Android (output only). Packages in beta for C++ Builder and Lazarus for easy build and install. MIDI (Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing and recording music (Wikipedia). This package provides 3rd generation of components to simplify communication with musical instruments, developed with high-performance in mind. The package also comes with a high-priority system timer and a MIDI clock component. You can register threaded observers, giving you MIDI events in real-time with timing, or non-threaded to respond in a UI environment.
The program is designed to measure and store on the HDD the amount of motion measured with the DirectX-compatible camera. The program also can capture video with sound and store them in compressed AVI files. The special feature of Motion Detector is its support of information exchange through UDP protocol. Motion Detector can send motion data in real time to other software for organizing real-time feedback in scientific behavioral experiments. It also can accept commands trough the network or from other software running on the same computer (through UDP) to start/stop video capturing. The program has a ring buffer in RAM to store prehistory - some amount of video before the UDP video capturing event can be saved in the file if needed. Name of the video file can be given in the UDP message or generated locally using auto-increment feature.
