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

datAxe is a software program designed to convert serial (RS232) data to the TCP/IP packets format and TCP/IP packets to serial data. While running on your PC, datAxe can receive serial data from a COM port of your PC and then send them out to a TCP/IP network through a TCP/IP socket connection on your PC. datAxe can also receive serial data from a TCP/IP network through a TCP/IP socket connection and send them to a serial port on your PC

The TGetDiskSerial is a VCL component. You can use it to read the serial number of hard disk easily. As we all know, this serial number is unique in the world. So this component is of great use, for example, you can use this serial number to creat an encrypt number.

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.

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 !

Virtual Serial Port Driver XP (VSPD XP) creates virtual com ports in your system and connects them via reliable virtual link, which emulates real null-modem cable. With VSPD XP you can connect one application to another using virtual serial ports pair. Applications will be able to exchange data. The latest version of VSPD XP now supports full baudrate emulation. New manual and examples are available.

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 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.

With Virtual Serial Port Driver CE you can connect one application to another using virtual serial ports pair for instantl data transfer. VSPD CE creates two pure virtual serial ports in your system which are virtually connected to each other. Virtual serial ports look and work exactly as two real serial ports connected via null-modem cable for Windows CE applications. Compatible with any Windows Mobile device with OS up to WindowsCE 5.0

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.

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.
