Do you want to make sure that your computer system is working as its best and that it is capable to receive complete communication information from other sources? It’s about time you try COM Port Data Emulator.

COM Port Data Emulator is a powerful COM port testing tool that is specially designed to emulate a COM or Ethernet device. It can create stream of data that are wrapped into data packets and sends it later on to a specific serial COM port. Its built in logging mechanism lets you manage the serial ports and its responses to the sent data.

COM Port Data Emulator suits best for software and network developers, network administrators, technical staff and engineers to help them analyze log file even without configuring complicated setups and settings. It lets you work efficiently and much more flexible to handle communication ports and log files.

If you are a software developer or a hardware engineer, you may often face situations when you need information about the ability of communication ports on a typical end-user system to handle large flows of data. If looking for a reliable COM port testing and analysis tool, look no further than COM Port Data Emulator!


This compact tool was created for emulating a COM or Ethernet device, generating a stream of adjustable intensity, wrapping it into data packets (RS232, TCP/IP or UDP) and sending to a specific serial (COM) port. Test data can be randomly generated or read from binary or text files and sent to the port repeatedly or on the ad hoc basis. The software supports flow control for COM and RS232 ports, full duplex mode and is capable of operating both as a client and a server over TCP/IP. The built-in logging mechanism enables users to analyze the work of serial ports and their responses to the data stream being sent. You can also check the line status and trace communication errors on the go. COM Port Data Emulator possesses high flexibility and allows users to test their applications with various baud rates (up to 115200), data bits, stop bits, parity types, flow control modes and other options.


The application can be used for any type of equipment operating over RS232/RS485/RS422 interfaces – measurement and monitoring devices, industrial controllers, radio stations, as well as a plethora of other devices, including other computers via z-modem cables.


In short, this program is a unique tool that will be a great asset in the arsenal of any serious developer working with COM and Ethernet interfaces. Great functionality, impressive flexibility and affordability are the key characteristics of this excellent software. If you would like to be sure that your product will work exactly the way you want it to and keep your customers happy, try COM Port Data Emulator – it’s a great value for your money and a great aide in your development needs!
