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 Driver XP4 creates any number of pure virtual serial ports pairs in your system which are virtually connected to each other. You can transfer files, exchange data or do whatever you want as it was real serial ports. For example, you can create virtual pair COM5-COM6. In this case all data sent by other applications to virtual serial port COM5 arrives at virtual serial port COM6 and all data sent to COM6 arrives at COM-port 5.

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.

Virtual Serial Port ActiveX allows your application to create additional virtual serial port in system and fully control it. Created virtual port looks absolutely like a real one for Windows applications. You can view parameters information of a virtual port, set by other application, view and control from your application data sent to virtual port by other applications and respond to them by sending your own serial data to virtual COM 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.

Share Serial Ports is an advanced utility for sharing real serial ports between multiple applications so that all applications will receive same data from real serial port simultaneously. It is achieved by creating virtual serial ports, exact copies of real ones. All virtual ports can send data to real serial port. You will be able to set port permissions to read, write or change control lines state for every application separately.

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 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.

Serial Splitter CE splits real serial ports into virtual ones. It is really useful if you need several applications to work with the same serial port on your mobile device (several apps to read from one GPS device). With Serial Splitter CE one program works with one virtual port, the other one with another port, etc., but in fact all of them work with the same split real port. You can create up to 20 equal virtual ports for splitting real ports.

Serial Port Monitor is a system utility for exploring the way OS works and monitoring how applications use ports. It can effectively be used for monitoring serial data exchange between serial devices and any Windows application, debugging computer connection with peripheral devices using COM port, for solving problems with serial (RS232/422/485) data communication control networks and devices, for software and hardware testing etc.
