Create and manage virtual serial ports from .NET and Visual Basic (ActiveX)
Using Virtual Serial Port SDK you can create a "new" serial port on your computer. This serial port is completely controlled by your application. Other 3rd party applications can connect to this serial port and believe it is a normal serial port.
Windows Mobile/Pocket PC, Windows XP/2k/NT and Windows ME/98.
Samples in C#, VB.NET and VB6

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.

Shared Serial Port - advanced utility to share real serial ports between applications so that all applications will receive/send data from/to real serial port simultaneously. Shared Serial Port creates virtual serial ports, which are same copies as real ones. Any virtual serial port will have the same name as the real one and any number of applications will be capable of using it at the same time.

Serial Port Mapper allows you to map any serial ports to any other serial ports. For example you install additional serial port expansion card to computer as COM7 serial port but your favorite software can work with COM1...COM4 ports only. To resolve this problem you can use Serial Port Mapper to map new COM7 port either to COM1 or to COM2...COM4. Now your software can open COM1 port (or COM2...COM4) but actually work with new COM7 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.

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.

This is a very simple command-line port mapper (port redirector).
The program is able to work in the hidden mode.

Free Port Scanner is a small, fast, easy-to-use and robust port scanner for the Win32 platform.You can scan ports on fast machines in a few seconds and can perform scan on predefined port ranges. This tool uses TCP packets to determine available hosts and open ports, service associated with port and other important characteristics. The tool is designed with a user-friendly interface and is easy to use.

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.

Advanced Lan Scanner is a small, easy-to-use, highly configurable network scanner for Win32. And it's fast. It's VERY fast. Advanced Lan Scanner uses multithreading technique, that gives it ability to scan more than 1000 elements per second! If used to scan ports, Advanced Lan Scanner can scan all 65536 ports in less that minute!

Advanced Port Scanner is a small, very fast, robust and easy-to-use Port Scanner for Windows. Powered with multithread scan technology, Advanced Port Scanner can scan hundreds of ports in just a few seconds! Also, it contains descriptions for common ports, and can perform scans on predefined port ranges.
