Modern computers and laptops are vastly superior to those manufactured in the past. Every new model offers faster performance or more storage capacity to address the user’s computing requirements. In most cases, a new computer will serve you better than an older machine.
One area where a recently purchased computer is lacking, however, is in the number or availability of serial ports. Many manufacturers have eliminated COM ports totally in favor of the more popular USB interface. This can pose a problem for developers or system administrators who need to interact with serial devices and applications
Even if there is a COM port on your machine there may be times when you need to access several serial devices simultaneously. What can you do?
We are going to show you six methods of adding COM ports to a computer that does not have any or needs more for a specific purpose. One is a software solution and the others involve the addition of hardware to accomplish the goal.
Adding COM Ports to Your System
Here are six options for adding serial interfaces to your Windows system:
- Simulate COM ports with a software application
- Convert USB to COM port
- Convert Ethernet to COM
- Adding COM ports over WiFi
- Conversion or branching of RS-232, RS-422, RS-485
- Adding COM ports via PCI, PCIe, ISA buses
1. Simulate COM ports with a software application
We believe the most effective and efficient method of adding COM ports is through the use of special software. Creating virtual serial ports is a more flexible solution and eliminates the need for additional hardware or cabling.
Virtual Serial Port Driver (VSPD) from Eltima Software is an excellent choice when you need to add COM interfaces to a Windows computer. It fully supports Windows 10 as well as previous versions of the OS.
Download VSPD to add an unlimited number of COM ports
Here are some of the Standard version’s outstanding features:
- Provides the ability to create an unlimited number of virtual serial port pairs;
- Fully emulates the settings of physical COM ports;
- High-speed data transfer through the virtual ports;
- Virtual null-modem schemes;
- Automatic re-creation of virtual ports on reboot;
- Windows kernel driver technology support.
The Pro version offers extended capabilities including:
- Splitting and merging physical or virtual serial ports;
- Setting individual read and write permissions for each port;
- Sharing a physical serial interface with multiple applications simultaneously.
VSPD is a reliable and convenient solution to the problem of adding serial ports to your Windows computer. There is no extra equipment involved and it does not require you to use another of your system’s hardware interfaces.
