Serial communication component Win/CE library for serial port communications from embedded Visual C++ (eVC++) programs. Controls multiple ports simultaneously and is fully thread safe, Includes 33 serial port functions plus XMODEM and YMODEM protocols, and a good selection of eVC example programs. Works with Windows/CE and all Pocket PC (PPC) platforms supported by eVC 3.0 and eVC 4.0. Can be used with Bluetooth serial and the Pocket PC emulator

Docklight is a test, analysis and simulation tool for serial communication protocols (RS232, RS485/422 and others). It allows you to monitor the communication between two serial devices or to test the serial communication of a single device. Key functions include: * Simulating serial protocols * Logging RS232 data * Detecting specific data sequences * Responding to incoming data.

Serial Splitter is an application, based on Windows kernel drivers technology and Eltima Virtual Serial Ports Driver. It allows you to share real serial port between several applications in a way that all applications will receive same data from one serial port simultaneously. It is achieved by creating virtual serial ports, which are same copies of real ones. Each application will think that it is working with serial port in exclusive mode.

Serial Port AX Control is a powerful ActiveX component that lets developers quickly and effectively organize work with serial ports. Serial Port AX Control makes communicating with external devices on rs232 connection really fast and reliable. Serial Port AX Control offers control of such devices as modems, bar code readers, navigational devices and others through a serial port. Includes examples for Microsoft VC++ and Microsoft Visual Basic.

Lightweight HTTP server and a script engine (like PHP or ASP) in one application .
It is a very good tool to control a device connected on a remote PC serial port
with a web browser. You can build a complete web interface for your RS232 device,
for example for a home automation box, a remote camera, a ham radio, writing html
and script pages. The script code is executed by the internal script engine, so is
very fast. PHP integration.

Basic like script engine for building Windows applications, targeted to serial and TCPIP comms.
Can handle not only basic tasks like open/close ports, write/read data, but more, like waiting for specific data to be received, process data, sending data in various modes.
Can open virtual instruments designed with Rack Designer(free) and use them in script.

The Windows/CE Standard Serial Communications Library for eVB (WSC4eVB) is a serial port communication library for Embedded Visual Basic (eVB) programs for the Pocket PC (PPC) and the Handheld PC (HPC).

WSC4eVB includes 33 serial port functions plus XMODEM and YMODEM protocols, and a selection of eVB example programs. Requires Microsoft Embedded Tools 3.0.

Serial Port ActiveX Control is a powerful component that lets developers quickly and effectively work with serial port. Use Serial Port component to easily communicate with external devices on RS232 connection, such as modems, bar code readers, PBX and so on. Serial Port introduces several extremely useful properties for detailed setting of serial port, numerous methods to write and read from port and events to control serial port state changes.
