Virtual terminal

This article is about the term standardized by Open system. For other uses, see virtual console and virtual terminal (payment processing).

In open systems, a virtual terminal (VT) is an application service that:

1. Allows host terminals on a multi-user network to interact with other hosts regardless of terminal type and characteristics,
2. Allows remote log-on by local area network managers for the purpose of management,
3. Allows users to access information from another host processor for transaction processing,
4. Serves as a backup facility.

PuTTY is an example of a virtual terminal.

ITU-T defines a virtual terminal protocol based on the OSI application layer protocols. However, the virtual terminal protocol is not widely used on the Internet.
