Open Source Serial Software

Serial terminal program for engineering. Ideal for development, reverse engineering, debugging, datalogging and capture, and automatic test. The website is a comprehensive manual for Realterm. It has an comprehensive ActiveX/COM automation support so it can be used a serial component by other programs. An extensive commandline interface supports batch files and simple automatic test programming. Commands can be sent to running instances, and commands can be stored and run in files. [ActiveX](http://realterm.sourceforge.net/index.html#ActiveX_Interface) and [Command Line](http://realterm.sourceforge.net/index.html#Command_Line_Parameters) commands are well documented. Sourceforge major releases are only made occasionally. To follow development versions see News and subscribe.

The Null-modem emulator (com0com) is a kernel-mode virtual serial port driver for Windows. You can create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. The HUB for communications (hub4com) allows to receive data and signals from one COM or TCP port, modify and send it to a number of other COM or TCP ports and vice versa.

Engineering, testing and debugging of serial communication. Supports RS-232/422/423/485 as well as TCP/IP Client/Server/AutoSocket, UDP/IP Client/Server/PairSocket and USB Ser/HID. Optimized for simple command sets of e.g. embedded systems.

This project provides a proxy that allows telnet/tcp connections to be made to serial ports on a machine.

setserial is a program designed to set and/or report the configuration information associated with a serial port.

ScriptCommunicator is a scriptable cross-platform data terminal that supports serial port (RS232, USB to serial), UDP, TCP client/server, SPI, I2C, and CAN. All sent and received data can be shown in a console and can be logged in an html and a text log. In addition to the simple sending and receiving of data, ScriptCommunicator has a JavaScript interface. This script interface has the following features: - Scripts can send and receive data with the main interface. - In addition to the main interface scripts can create and use their own interfaces (serial port (RS232, USB to serial), UDP, TCP client, TCP server, PCAN, and SPI/I2C). - Scripts can use their own GUI (GUI files which have been created with QtDesigner (is included) or QtCreator). - Multiple plot windows can be created by scripts (QCustomPlot developed by Emanuel Eichhammer is used)

Multiplatform Serial Port Module for Python (Win32, Jython, Linux, BSD and more)

SerialToIP is a simple Terminal Server software providing transparent pipe either in TCP server or TCP client socket mode from TCP/IP to a pre-configured serial port. Implemented in C# for .NET 2.0 so the command line version could work in Mono-runtime as well.

LCD Smartie displays information on your LCD/VFD. It supports LCDs with a Hitachi HD44780 Controller via parallel port & Matrix Orbital and Crystalfontz serial/USB LCD/VFDs. Info includes: CPU temps, fan speed, the BBC World News, Stocks indexes etc.

A versatile test tool running on Windows/Linux/macOS/Android. Works as data transceiver/realtime plotter/shortcut/file transceiver. Supports serial port, Bluetooth SPP client/server, Bluetooth LE client, TCP client/server, UDP. Homepage: https://github.com/wh201906/SerialTest

serialconsole (sc) is a minimal terminal program allowing to use one machine to access the serial console of another machine.

Allows you to redirect all communication data from RS232 compliant serial port device into a text file for further analysis. RS232 Data Logger redirects data from any available serial port/ports and works under Virtual Machine.

Serial port assistant This is only a read-only mirror repository. Main repository: https://github.com/KangLin/SerialPortAssistant

Qodem is a a terminal emulator that resembles the BBS-era Qmodem. Includes phonebook, scrollback, capture, X/Y/Zmodem, Kermit, ANSI (+ music) / Avatar / VT102 / Linux emulation, Unicode, and keyboard macros. Connects over serial, ssh, telnet, rlogin.

This project has moved to GitHub. Search for QST there. The project will not be updated here, since SF is hard to work with. A QT-based serial terminal program. Works on Linux or Windows. Basic serial terminal for use with embedded systems.

A very simple software that bidirectionally forwards COM (serial) communication through a TCP/IP connection. Typical application: you want to use 2 devices (that are connected to each other using RS232 protocol), remotely. With this software you'll be able to operate them in different locations. Act as TCP server / TCP Client. Supports multiple clients. LICENSE: Apache License Version 2.0, January 2004 http://www.apache.org/licenses/

A portable library to access braille displays.

This program will read a file (or stdin) containing a list of AT commands. Each command will be send to the modem, and all the response for the command will be output to file (or stdout). Example, to hang up any ongoing call: $ echo ATH | atinout - /dev/ttyACM0 - ATH OK $

Serial Port to TCP/IP Connection Mapper. Maps sockets to serial ports.

A gtk-based serial terminal optimized for logging and file capture.

SerialPortNet is an open source serial port communication library for Microsoft .NET. It's written in c#, implements complete .NET 2.0 specifications, and is designed to allow for multiple OSes and add-on 3rd party Serial to Network adapters.

tcp2com creates a bridge between a TCP socket and a serial port (COM). The program runs as a service under Windows NT. With tcp2com, you can telnet into any device you may have plugged into your COM port.

Ponticulus (a virtual COM-port over TCP/IP redirector) allows synchronous connecting and disconnecting to a remote serial port (e.g. on an embedded device). It was initially based on com2tcp, part of the com0com project. (http://com0com.sourceforge.net/)

The MtxOrbCtl program allows you to control a Matrix Orbital Serial LCD screen from the command line. It is designed to be used in conjunction with shell scripting to show the status of boots, etc.

Current stable release: version 1.3 (2022-11-10) More info in wiki.
