Let’s take closer to Virtual Serial Port Driver benefits
- Any number of virtual COM ports
With this null modem RS232 emulator, you can create an unlimited number of virtual com ports and assign them any name, including the name of an existent serial port. Created ports are located in “ports” group in Device Manager so that they are visible and easily recognizable by the system. You can define which application can access a particular port, your real hardware serial ports remain free.
- Real ports settings emulation
These virtual com ports emulate all the serial port functionality, including Baud rate, data bits, parity bits, stop bits, etc. RS232 null modem driver uses advanced Windows kernel driver technology, which ensures WDM, WMI, Power Management, PnP, etc. support. Virtual COM Port from Eltima emulates a serial line break and it is fully compatible with API COM and supports all Windows messages.
The virtual serial ports created with Virtual Serial Ports Driver emulate and support all standard hardware signal lines (DTR/DSR, RTS/CTS, RING, ERROR, DCD, etc.). Similar to the connection via real null modem cable, DTR of the local port is connected to DSR and DCD of the remote port, and RTS of the local port is connected to CTS of the remote port. Moreover, you can choose loopback pinout or customize it according to your hardware configuration.
If you like the idea of using a serial port simulator but are not sure which solution to choose, an open source kernel-mode virtual serial port driver com0com will definitely be a good choice. The program is able to provide a COM interface for device emulation apps. What this means in practice is that a device emulation program connects to one port of a serial port pair while the other port is used by Windows app (that needs to talk to the device). This way, for example, you can share faxes over IP. All you need to do is connect Windows Fax application to t38modem via virtual COM port pair. Com0com support for Windows 10 is another advantage of the app.

of Virtual Serial Port Driver and Null-Modem Emulator
Virtual Null Modem by AGG Software
Still trying to find an efficient emulator for serial communication? Easy-to-use Software developed by AGG is designed to help you resolve any serial communication issue. The solution offers high hardware and software reliability (drivers are tested with the verifier under Windows XP SP2), fast connections via virtual null modem cable, full independence of virtual COM ports form hardware serial interfaces available in the system, and support for WDM, WMI, Power Management, PNP, etc.
Free Virtual Serial Ports
Ever wished you could emulate custom plug-and-play COM ports and I/O ports interfaced by 16550 UART? Well, that’s what Free Virtual Serial Ports solution is focused on. This free application lets you create a virtual copy of a hardware null-modem cable with DB-25 or DE-9 connectors. The program lets two RS-232 DTE devices communicate with each other without using modems or any other DCEs. More than that, the app works exclusively in user-mode which ensures the stability of its performance.
After comparing the functionality of all the aforementioned software tools, you can see that Virtual COM Port Emulator by Eltima stands out for its versatility and ease of use. Such advantages as clean and friendly interface, efficient customer support, high level of data protection, possibility to create and remove virtual ports in real-time, etc. make Eltima’s solution an extremely effective tool able to cover a great variety of port emulation needs.
Virtual Serial Port Kit
If all you need is a handy solution for establishing seamless communications between two serial apps, you can try Virtual Serial Port Kit. This software will let your communications programs talk to each other over a reliable virtual COM port connection.
The main goal of the tool is to provide your system with virtual COM interfaces through which serial apps can enable their two-way data exchange. The scenario is extremely simple, the software just creates two virtual serial ports (exact copies of hardware interfaces) on your computer, let's call them COM1 and COM2, and then one of your apps connects to COM1 and the other one occupies COM2. The data transmission starts once the virtual ports are opened on both sides by the apps.
The additional advantages offered by Virtual Serial Port Kit include support for several null-modem pinouts with different handshakes used for the communication process and the ability to emulate loopback plug. Plus, you won’t need to reconfigure all created virtual ports upon system startup, all settings will be renewed automatically even prior to user's logon.
