Shared Serial Ports - HHD

Serial port splitting software for easy sharing of one serial device among several applications HHD Software Shared Serial Ports is a software utility that allows you to manage data flow of a single COM port or device within multiple serial communication applications in different ways. It supports three basic modes of operation: Serial Port Splitter, COM Port Share and Serial Port Mapper.

1. Serial Port Splitter - creates several virtual com ports, all connected to the specified original physical serial port. Each virtual port can be accessed by your serial communication program.
2. COM port share - creates one virtual port, connected to the specified original physical com port. This virtual port is accessible for multiple serial applications running simultaneously.
3. Serial Port Mapper - creates software serial port aliases for hardware serial ports and maps physical COM port to the new port number. Rename port to match name used by legacy serial app.

Virtual ports fully emulate all the functionality of the original serial port. Our port virtualization technology supports all Plug-and-Play RS232, RS422, RS485 ports as well as legacy and even virtual serial ports. Serial ports created by PnP USB to Serial converters/adapters are also supported. There is a developer API for easy integration with your projects.

It provides you with clear and intuitive user interface, detailed documentation and requires no programming skills to start using it. Download it now and start cloning serial ports in a few seconds!

Functionalities Due to the fact that the design of the Windows operating system allows only one application to open the serial port exclusively, there are certain inconveniences in working with serial devices. Our software-based solution will help you to get around these inconveniences without the need for additional serial equipment.

Our serial port sharing and splitting solution allows you to:

Split serial port in order to make it accessible by multiple serial communication applications simultaneously. Clone serial port and then forward/redirect serial data from original com port to any number of virtual serial ports, duplicating original serial data stream. Fork com port data to another serial port by creating port alias. Each virtual serial interface completely replicates the features, options and configurations of the original port. It fully emulates all the functionality of a hardware serial port, including baudrate, databits, parity, stopbits, etc. It also allows you to control a serial dataflow by emulating hardware control lines. (DTR, DSR, DCD, RTS, CTS and RI).

There are following com port flowcontrol emulations are supported by this application:

No flow control Software flow control (XON/XOFF flow control) Hardware flow control (Rs 232 RTS/CTS flow control, DTS/DSR flow control) Custom flow control
