Serial Port Splitter Description

Allows to share dataflow of one serial port between several applications

Serial Port Splitter allows to share dataflow of one COM port between several applications or vice versa to join dataflow of several COM port devices to one application. Such program universality is achieved by means of virtual serial ports technologies. Moreover Serial Port Splitter allows to setup READ/WRITE or READ ONLY mode for splitted ports and READ/WRITE or WRITE ONLY mode for joined serial ports.

Program features:
- One COM port can be splitted up to 254 virtual ports
- One COM port can be opened by several applications at the same time
- Several COM ports can be joined to one virtual port
- READ/WRITE or READ ONLY mode mode for splitted serial ports
- READ/WRITE or WRITE ONLY mode mode for joined serial ports
- Once created virtual serial ports are operable at each system startup
- Compatibility with Hyper-Threading Technology
- Compatibility with PnP and WMI technologies
- Compatibility with VMware software
- Hot program install - no system reboot is required
- User friendly interface

Common Problem

As soon as the necessity to work from several applications with a device connected to COM port arises, you face problems.

The point is that the operating system allows accessing COM port to only one application simultaneously.

As a result we have created a powerful application Serial Port Splitter that allows you to get access to a device connected to a COM port from several applications simultaneously.
How It Works

Serial Port Splitter creates virtual COM ports that are the exact copies of the specified physical COM port. Now, any program can work with its own virtual COM port not hindering other programs.

Data written to physical COM port get to all the virtual COM ports. And vice versa, the data written to virtual COM ports gets to the physical one.
Serial Port Splitter
Real Usage Example

Bob took his GPS-receiver connected to the laptop and went to the countryside by car. He wants to track his own location on the map and writes his route for further examination. At the same time Bob wants to see 3D model of place where he is at present.

Unfortunately Bob does not have the multifunctional program, which would solve all his tasks. That's why he uses three different programs.

Using Serial Port Splitter he splits physical COM port to which GPS-receiver is plugged into three virtual COM ports. Then he configures each application to use its own virtual COM port.

Now all three programs retrieve data from one GPS-receiver simultaneously and everything works fine like never before.
What Serial Port Splitter Can Do

There are 3 things Serial Port Splitter can do: splitting, sharing, joining.
Splitting
Serial Port Splitting

This feature allows creating virtual COM ports that are the exact copies of specified physical COM ports. All the data written to physical COM port get to all virtual COM ports. Data written to a virtual COM port get to physical COM port.

In such a way, by means of virtual COM ports, several applications can exchange data simultaneously with the same device connected to a physical COM port.

At the same time, there is a possibility to configure ports access permissions, COM ports settings and so on.
Sharing
Serial Port Sharing

Question: Is it possible to work with the same COM port without splitting it to several different virtual COM ports?

Answer: It is possible! There is a Share feature that is intended to accomplish it. Any physical COM port, being shared, can be opened by several applications simultaneously.
Joining
Serial Port Joining

From time to time it is necessary to write the same data to several physical COM port from one application. This task can be accomplished using Join feature. The program creates virtual COM port and forwards serial data from it to several physical COM ports.

Read Usage Examples.
Access Permissions

Sometimes it is necessary to limit access to a COM port for several applications (e.g. some programs are to only read data from the COM port and some programs need full access to the COM port). Serial Port Splitter supports such mechanism.
OEM License Benefits
