The Network Virtual Terminal (NVT) is a representation of a basic terminal and provides a standard that the computers on either end of a Telnet connection are assumed to follow. It defines how data and commands are sent across the network. Thus, NVT allows interoperability between Telnet and a variety of heterogeneous computers and operating systems. It consists of a virtual keyboard that generates user-specified characters and a printer that displays specific characters. Clients and servers can map their local devices to the characteristics and handling conventions of an NVT and can assume that other servers and clients are doing the same.
