Virtualization is used by many organizations to extend the capabilities of their computing environment. Virtual machines offer the flexibility of running multiple operating systems on a single physical computer for the purposes of testing or using specialized software applications. The virtual guests share the host’s disk space, memory, and CPU, minimizing the required physical resources.
Virtual serial port technology enables you to connect a virtual machine to any peripheral device attached to a local computer’s COM port. Enabling the serial port in the virtual machine is done differently based on the type of virtualization package you are using. In some cases, this is done with a few minor configuration changes from within the VM. Other solutions require the use of third-party communication software.
This article talks about a number of methods that allow COM port to virtual machine access in Hyper-V and other virtualization platforms.
