In a nutshell, the virtual machine (or VM for short) is an emulated computer system that imitates the configuration and operability of a real PC.
The software-based VM (also known as full virtualization VM or system VM) is all-in-all a separate fully-functional operating system inside the real host OS. It’s really handy to have one of those if you, for example, want to test your software product on different platforms, or need to use an application incompatible with your current OS, or would like to create an OS backup.
There are also hardware-assisted VMs, and virtualization-specific hardware, widely used by present-day hypervisors (VM monitors) that will allow you to run several isolated operating systems or programming environments on a single physical machine.
In some scenarios, you may need to use your serial printer, modem, or some other device connected to a COM port from your virtual machine. You can also use a serial port in a virtual machine for debugging data transferring to a host PC or another VM. For such purposes, you’ll have to enable a COM port in a virtual machine first.
Serial to Ethernet Connector (SEC) allows you to access the serial port in virtual machine and get full advantages of using COM port functionality. For example, developers rely on serial ports to interface with kernel debugging software. But it is possible to place a virtual serial port and carry out kernel debugging. This means there is no need for a real computer to be connected.
So what needs to be done to enable a COM in a virtual machine? In a best-case situation, your virtualization software can be configured to access the serial devices of a host machine. In a not-so-lucky picture, it doesn’t have an embedded function for a COM in a VM, so you’ll have to purchase an extra software application that will grant you access to serial ports through the network.
Well, here we will describe the most handy method to work with COM port in virtual machine.
Serial to Ethernet Connector enables you to easily access serial ports in a virtual machine. Users of VMware, Citrix XenDesktop, Hyper-V, and other virtualization platforms can create and share virtual serial ports with the same functionality of a physical COM interface. All you need to do is download the software to the host and guest machines that will share the serial port.
That’s all you need to do to access a serial port in a virtual machine. After the client connection is established, Serial to Ethernet Connector links the host’s physical port to the virtual interface. The guest virtual machine obtains full functionality over the connected serial device.
One of the simplest ways to connect a COM port in a virtual machine is (in Windows or Linux) by using the Serial over Ethernet Connector approach. The Serial to Ethernet Connector software tool can provide you with access to COM in Hyper-V, VMware, and even VirtualBox.
The computer a shared device is connected to, such as remote machine or host, will function as the server. The virtual machine connects to it as soon as the remote access to serial devices is established and acts as the client.
Now, if you’re wondering how to enable a serial port in a virtual machine over the network, you will need to download and install the app onto the guest operating systems as well as on the host. This will aid the creation of client and server connections through the software. Serial to Ethernet Connector opens up access to serial port in VirtualBox, VMware, and Hyper-V.
