Such adapters connect to classic devices via at least one serial port, and allow to control this device via a network. The network is typically Ethernet, sometimes also WLAN and even control via Internet is possible.

But most adapters come with a Driver or Com Port Redirector, by which the remote serial port appears as a virtual Com Port installed in the computer.
