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.

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 Port Sniffer is a powerful advanced ActiveX Control that allows your application to sniff (fully monitor and edit data flows) serial port in your system. Serial Port Sniffer ActiveX Control detects all serial port activity in your system, all applications that work with serial port and all the data that is being sent and received can be easily monitored with Serial Port Sniffer ActiveX Control within your own application.

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.

You can connect data collection serial devices: bar code scanners, modems, sensors, gages, RF equipment, telephone PBX systems, laboratory or industrial instruments, and so on - to the serial ports of your computer to deliver that data anywhere over any TCP/IP based network. Program creates up to 254 virtual serial ports at a time. Physical COM ports located on remote computer can be connected to host computer over the network as well.

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 !

To monitor (bi-directional) Serial communication RS-232 between two devices without physical cable, you can use the freeware Bill Serial Monitor. This freeware enable you to view, log, test and analyse the activity of the serial RS-232 port. If you want to monitor the serial protocol of two different serial devices you can use our Protocol Analyser function. DSR, CTS, DTR and RTS can also be controlled

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.
