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.

Serial to Ethernet Connector is an advanced software solution developed to share serial port devices over TCP/IP network. Thus, any serial port device connected to COM port at local PC could be accessed from anywhere in the world via internet, for example. When the attached serial port device sends communication data it will be actually transmitted over TCP/IP network. Such behavior is achieved due to the use of virtual serial port technology which emulates standard COM ports. In that case Windows OS treats virtual serial ports in the same way as real ones therefore you are no longer limited to just two real ports (any number of physical ports you have) per system and may create COM port connections without occupying any real serial port. Formerly known as VSPD.Net, Serial to Ethernet Connector has a completely new interface and greatly revamped engine. It allows you to use three different types to connect to remote computer. The first type is port-to-port connection, which lets you connect two computers through TCP/IP network. In this way you can emulate virtual null-modem cable connection. Serial to Ethernet Connector allows you to customize remote serial port settings locally or dynamically fetch these settings from the remote end. Second type is the port-to-TCP client, which allows you to connect to remote server and send/receive communication serial data over TCP/IP network. Once connection is established, all data sent from remote serial port device, attached to the server, will be genuinely delivered to local serial port where it can be further processed. The last type is the port-to-TCP server which allows you establish multiple connections to local serial port device and redistribute COM port device data all over the world. Server listens to all incoming connections at the defined TCP port and redirects input/output serial data to TCP/IP network. Serial to Ethernet Connector can be easily configured for current demands.

Network Serial Port Kit allows you to connect any serial port devices over the TCP/IP network or Internet. Creation of local virtual serial ports pairs are available as well.

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. You can connect data collection serial devices: bar code scanners, modems, sensors, meters, 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.

For example you can convert usual PC to "Serial Port Server" so then you can connect any serial device directly to a TCP/IP network and communicate with that device from any other PC in the same network or across the Internet. This allows you to use existing Windows based serial communications software to send and receive data to remote serial device across a network.

VSPD Mobile Phone Edition is a brand-new generation of already popular driver for mobile devices released by Eltima more than a year ago. Now we bring a totally new level of serial emulation for SmartPhones based on Windows Mobile platform! VSPD Mobile Phone Edition is capable of creating up to 20 pure virtual serial ports in your mobile system, this results in up to 10 virtual serial ports pairs available for testing and integration. Two ports in a pair are connected via a virtual null-modem cable and fully emulate real serial ports that may or may not be present in your device. You can select any port numbers (between 0 and 9) for virtual serial port pair as well as decide whether to use COM or VSP prefix. For example, you can create virtual pair COM5-COM6 (or VSP0-VSP9). In this case all data sent by other applications to virtual serial port COM5 (VSP0) will be received at virtual serial port COM6 (VSP9), and all data sent to virtual serial port COM6 will be received at virtual serial port COM5 (VSP0). This can be seen if you run two terminals connected to both sides of the virtual serial ports pair. Everything typed in the first terminal will appear at the second one. Virtual serial ports pair can be used to transfer files, other data and do anything as if there are additional real serial ports in your smartphone. With Virtual Serial Ports Driver Mobile 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 software.

RTKF puts a powerful registry cleaning tool into your hands. It quickly finds unwanted registry data. You can safely strip out "orphaned" entries and other "rubbish" left behind by "trial" and other software. Most "uninstall" programs DO NOT really clean up after their parent programs. With RTKF you can streamline the registry and perhaps even improve Windows' speed and reliability. Registry "debris" from improper uninstallation routines is a major problem in Windows. RTKF helps users address this issue by giving them software that finally lets them take control of those sometimes "hidden" registry entries used by trial period software. Unfortunately this software has an annoying habit of leaving behind data which adds to the size of the registry. Install and then remove a few of these programs and you'll find your system getting slower and perhaps even crashing more. Removing these useless entries reduces Windows' memory needs and has other benefits as well.

Virtual Serial Ports Driver CE creates up to 20 pure virtual serial ports in your mobile system, this results in up to 10 virtual serial ports pairs. Each pair has 2 ports that are virtually connected to each other. For other applications, virtual serial ports will be seen exactly as two real serial ports connected via virtual null-modem cable. You can select any port numbers for virtual serial port pair as well as change their names from COM to VSP. For example, you can create virtual pair COM5-COM6 (or VSP0-VSP9). In this case all data sent by other applications to virtual serial port COM5 (VSP0) will arrive at virtual serial port COM6 (VSP9), and all data sent to virtual serial port COM6 will arrive at virtual serial port COM5 (VSP0). This can be seen if you run two terminal programs available for your OS and connect one of them to virtual serial port 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 if there are more real serial ports in your embedded device. With Virtual Serial Port Driver CE 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.
