Serial Port Control is an inexpensive royalty-free component. You can use it with any development environment, such as VB, VB .Net, VC++, C#, Delphi, etc. Just put it on a form and vou've got all the functionality you need to access an RS232 port. The event driven architecture makes it a snap to use. Just define a function in your program and it will be triggered automatically when new data is available through the port.

SRedirect is a command line utility that allows a remote TCP/IP connection to a serial port. SRedirect redirects all RS-232 data from a TCP/IP port to and from the local serial port. SRedirect creates a server for ONE local serial communications (COM) port. SRedirect allows connection of a client application. SRedirect transfers data in both directions between the connected client and the local COM port.

Eltima Virtual Serial Port Driver 6.0 enables you to create any number of pure virtual serial ports in your system connected into pairs via virtual null-modem cable without using any real serial ports. Virtual Serial Ports appear to operating system or any Windows application as "standard" hardware serial ports. This is helpful for serial software and GPS software developers, telecommunication and data transmission specialists.

To monitor (bi-directional) Serial communication RS-232 between two devices without physical cable, use Bill Serial Monitor. This software allows you to view, log, test and analyse the activity of the serial RS-232 port. To monitor the serial protocol of two different serial devices. DSR, CTS, DTR and RTS can also be controlled
No programming or additional hardware required !

Creates virtual COM ports directly from your own programs and fully control them! Virtual ports look like real hardware serial ports for all serial communications applications. On the other hand, developer API allows your program to access data written to virtual serial port by communications application and to respond with your own data. OEM license allows you to distribute this ActiveX control as a part of your software.

Eltima Serial Port Terminal is an ideal tool for testing, debugging and troubleshooting serial port devices. It lets you work with numerous number of ports simultaneously, both serial and virtual ones. You can easily alter baudrate, databits, parity, stop bits, flow control parameters and dynamically apply these changes to serial port settings on the go. You can always check for history of typed commands.

COM Port Toolkit is an integrated serial communications testing toolkit. It sends user's data to and receives one from a device and records all transfers to a log.

You can test equipments serial communications protocol by hand: feed it input, check the output.

COM Port Toolkit can capture serial communications between the device and the software by using special serial port driver.

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.

Virtual Serial Port ActiveX Control is a powerful tool for professional developers that allows your application to create custom additional virtual serial port in system and fully control it. Created virtual serial port looks like real serial port for other Windows applications. From your application you can control data sent to virtual serial port by other applications and respond to them by sending own data to virtual serial port.

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.

HS COM is a software library (with full C source code) that allows a calling user application to access serial communication ports (COM devices) under 32-bit MS Windows operating systems. It allows to transmit data, receive data and control line signals (such as RTS and DTR).

HS COM library provides a convenient "packaging" to standard Win32 API by exposing only a few simple API services to a calling application

HS XMODEM is a software library in C (supplied with full source code) that provides a programmer with the off-the-shelf support for XMODEM protocol data transfer capability. Support for both sender and receiver are provided. Other features include 1024 block size vs 128, CRC vs checksum, configurable timers and retries.
