Virtual Machine Serial and Parallel Port Support

Virtual machines support serial (COM) and parallel (LPT) ports.

• Up to four serial (COM) ports are supported. Output can be sent to serial ports, Windows or Linux files, or named pipes.
• Up to three bidirectional parallel (LPT) ports. Output can be sent to parallel ports or host operating system files.

Note: Physical parallel port support is removed in VMware Workstation 17.6 and later on the Windows platform.
