A Virtual Null Modem is a program or software solution that can emulate multiple RS232 port pairs that are connected with the help of a null modem cable.
It’s possible to create several virtual serial ports practically similar to actual ports like COM127, COM11, COM10, etc. These are connected by the virtual null modem cable in pairs. A Virtual Null Modem lets you create any number of ports based on the system resources you have.
So, if you need to use a virtual null-modem connection and are looking for a solution to do that, read on. Virtual Serial Port Driver and Null-Modem by Com-0-Com are two great options for this.
Let’s compare them to find which among them is better suitable for your needs.
Electronic Team’s Virtual Serial Port Driver is an advanced virtual null-modem software solution. This commercial, professional-grade tool can easily create multiple virtual COM port pairs connected through a virtual null modem.
Next, these port pairs facilitate a virtual communication bridge to enable data from an application at one end of the pair to get transmitted and immediately received by another application at another end of the pair.
Virtual Serial Port Driver offers a rich set of features to solve issues that are caused by the absence of serial physical interfaces on modern systems. It allows you to test programs via support control signals, high transmission speeds, and virtual ports. As it can create ports immediately, it lets you work with these ports before the PnP manager identifies the new ports.
Some of its key features include:
So, if you want to leverage a high-quality virtual null modem emulator, Virtual COM Port Driver can be a great option to meet your needs.
Com0com’s Null-modem emulator is a kernel-mode, open-source virtual serial port driver. It has a GPL license and is available for free use.
This emulator lets you create unlimited pairs of virtual COM ports. You can use any of these pairs to connect an application (based on a COM port) to another application. Here, each port pair offers two COM ports. One port’s output will be the input from another port, and vice versa.
Furthermore, you can use Null-modem emulator to provide a serial interface for a device emulator and COM port redirectors.
Hub4com is a part of com0com that lets you manage signals and data from a serial device using multiple applications. For example, many apps can easily exchange data from a single GPS device. In addition, hub4com allows using a remote computer’s real/physical serial ports as if these ports are actually present on a local computer.
Let’s compare key features of Null-modem emulator by com0com and Virtual Serial Port Driver by Electronic Team. This will help you make a better decision. The below table has the benefits of using the paid software vs free and open source.
Virtual Serial Port Drive (VSPD) is a professional-grade virtual null-modem software that’s efficient and comes with useful features. It not only lets you create numerous virtual COM ports quickly but also provides you with great options to enable full serial port emulation.
