79722 May 2026

Serial Port Emulator will allow you to create virtual RS232 ports linked together in pairs via the virtual null modem connection. The absolute advantage of the virtual ports created with our software is that data transferred by the applications that open these ports on either side of the pair, is written to one virtual COM port and instantly read from another one.

Every created virtual port will be treated by the operating system and therefore any Windows software as the real COM port, meaning that it will support the same settings. When the virtual serial port pair is added, it appears in Windows Device Manager, what is more, it is automatically recreated on system boot, even before logging into your Windows user account. Virtual Serial Port Emulator can be integrated into your own application (SDK license) allowing you to create and manage virtual serial ports right from your piece of software.

Common problem

Let’s imagine that you need to establish a serial connection between 2 applications. Usually, you will require two hardware COM ports connected with the null-modem cable, which is an unaffordable luxury nowadays, considering that current PCs have only one serial port or none at all. With COM Port Emulator you can forget about any additional hardware equipment since virtual RS232 ports do not require it at all.

How COM Port Emulator solves it

COM port Emulator is a unique piece of software, which can create an unlimited number of RS232 ports linked with the virtual null-modem cable. The virtual COM ports created with our software are indistinguishable from the real ones, and at the same time are much more efficient: the connection between the virtual COM ports is much faster than real null-modem cable connection and only depends on your processor performance.

COM port emulation in Electronic Money Institution
S-money is the electronic money organization which issues electronic money directly to the end user, who interacts with it through various canals (the smartphones, web-sites, point of sale terminals).

Q: What difficulties forced you to look for such kind of software?

Armand dos Santos: Some of our customers were still using the obsolete POS terminals, so we had to search for the way to emulate serial port pairs to enable the communication between such devices and the S-money application. For us, it was crucial that the created virtual COM port Windows recognizes as the real one. Moreover, we were looking for a solution that could be integrated into our own software written in Java.

Q: How did you find out about COM Port Emulator by Electronic Team?

Armand dos Santos: The search query via Google has shown your solution, which eventually suited our use case the most.

Q: Have you tried any other software to achieve your goal before selecting Electronic Team’s solution? Could you please tell why you preferred our product?

Armand dos Santos: Of course, we checked a few other products but we failed to find one which could be easily and fully integrated into our own application. Besides, after conducting some tests we came to a conclusion that only COM Port Emulator meets our functional and quality requirements.

Q: Could you please elaborate more on how you use our product?

Armand dos Santos: We use your software to emulate RS232 ports connected in pairs with our custom application in order to enable serial communication between the legacy POS systems and our custom application.

Q: How did you benefit from using COM Port Emulator?

Armand dos Santos: Complete integration of your solution made it extremely easy for us to support thousands of our customers’ legacy cashier systems.
