Null Modem and Virtual Serial Port Driver Xp4 Software for Windows

Eltima Serial Splitter
$99.95 - Serial Port Software

Eltima Serial Splitter establishes serial connection and implements data transmission between COM-ports and applications, or any kind of serial port devices.When Splitter is used to split only real ports and connects them to other physical serial ports, no virtual ports are created. Virtual serial ports are based on a technology by Eltima and are used to connect several applications to the same COM-port. Splitter creates several virtual copies of a COM-port.Applications refer to corresponding virtual ports (for instance, COM2, COM3), which send data to the real COM1 and to a connected device. Then, all data a real port receives from the device is transferred to the applications via virtual ports. Serial Splitter splits one com port (either real or virtual) into several ones (real or virtual ones), which are exact copies of the original port in the system. For instance, it splits real COM1 into virtual COM2, COM3, COM4 ports. To create a pure virtual ports pair you might also try VSPD XP. Here's a real-life example: A sale on a cash register is made. The cash register sends text via a serial port (COM1) to a computer. The software on the receiving computer takes the text from the serial port, and prints some of it to a video file. Using Serial Splitter one-to-many ports splitting, this information can be viewed from several computers or applications. Eltima Serial Splitter joins any number of COM ports into one serial port, allowing information from several devices to be received by a single application connected to the port at the OUT side of the bundle. For example: 100 websites are hosted on 100 computers. Via null modem a certain data is delivered from these computers to a PC with a microcontroller. On this PC Eltima Serial Splitter joins com-ports and sends all dataflow to a one virtual serial port. Single application receives and represents all information about the status of a 100 server hosts simultaneously.

Virtual Serial Port SDK
$49 - Franson

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 physical port. In this way you can emulate all kinds of hardware normally connected to a serial port, emulate a null modem, and so on.

Virtual Serial Port SDK is available for .NET and ActiveX, on all Windows platforms Windows Mobile/Pocket PC, Windows XP/2k/NT and Windows ME/98. Samples in C#, VB.NET and VisualBasic 6.0 are included.

Virtual Serial Port Driver XP4
$111.95 - ELTIMA Software GmbH

Virtual Serial Port Driver XP4 creates two pure virtual serial ports in your system which are virtually connected to each other. For other Windows applications, virtual ports will be seen exactly as two real serial ports connected via null-modem cable. You can select any port numbers for virtual pair. For example, you can create virtual pair COM5-COM6. In this case all data sent by other applications to COM5 will arrive at COM6, and all data sent to COM6 will arrive at COM5. This can be seen if you run two HyperTerminals (or any other Windows terminal programs) and connect one of them to COM5 and other one to COM6. Then, all you type in first terminal will appear at second one. Of course, you can transfer files, other data or do whatever you want as it was real serial ports. With Virtual Serial Port Driver XP 4.0 you can connect one application to another using virtual serial ports pair. Applications will be able to exchange data. This solution can be used, for example, for GPS simulation programs.

Advanced Virtual COM Port
$79.98 - KernelPro Software

Advanced Virtual COM Port is the first software of its kind which includes both local and network
virtual COM port functions.

It can share your real COM ports or it can create virtual COM ports and connect them with a
virtual null-modem cable locally or through a TCP/IP network or the Internet.

You can connect to a shared port and use it just like it is on your machine. Virtual serial ports
created by the program look and work the same way as real ones look and work.

Main features:
- Virtual COM Ports appear to the system and applications like real ones
- Virtual COM Ports work like real ones
- 64-Bit compatible (AMD64)
- Hot Virtual COM Port creation and removal (no need to reboot the computer)
- Once created, Virtual COM Ports persist in the system until you remove them
- No need to have physical serial ports (except for the physical ports sharing function)
- Higher data transfer rate than on hardware serial ports
- Up to 255 Virtual COM Ports can be created
- PnP, WMI support
- Flow control emulation supported
- Easy port state monitoring
- Ability to temporarily remove all ports without losing their configuration

Virtual Serial Port Driver XP4.5
$111.95 - ELTIMA Software GmbH

Virtual Serial Ports Driver XP creates two pure virtual serial ports in your system which are virtually connected to each other. For other Windows applications, virtual ports will be seen exactly as two real serial ports connected via null-modem cable. With virtual ports created by Virtual Serial Port Driver XP you can connect applications to each other and exchange data between them without occupying your real serial ports and using hardware wiring. Virtual link between virtual serial ports is much faster then real null-modem cable connection and depends on your processor speed. The latest version with new manual and examples now supports full baudrate emulation. With user-friendly GUI and on-the-fly help of Virtual Serial Port Driver XP it's very easy to configure a virtual serial ports pair.

Virtual Serial Ports Driver XP
$111.95 - ELTIMA Software GmbH

Virtual Serial Ports Driver (VSPD) creates two pure virtual serial ports in your system which are virtually connected to each other. For other Windows applications, virtual ports will be seen exactly as two real serial ports connected via null-modem cable. You can select any port numbers for virtual pair. For example, you can create virtual pair COM5-COM6. In this case all data sent by other applications to COM5 will arrive at COM6, and all data sent to COM6 will arrive at COM5. This can be seen if you run two HyperTerminals (or any other Windows terminal programs) and connect one of them to COM5 and other one to COM6. Then, all you type in first terminal will appear at second one. Of course, you can transfer files, other data or do whatever you want as it was real serial ports. With VSPD you can connect one application to another using virtual serial ports pair. Applications will be able to exchange data. This solution can be used, for example, for GPS simulation programs.
