Computer application for remote access
In open systems, a virtual terminal (VT) is an application service that:
- Allows host terminals on a multi-user network to interact with other hosts regardless of terminal type and characteristics,[1]
- Allows remote log-on by local area network managers for the purpose of management,[2]
- Allows users to access information from another host processor for transaction processing,
- 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.
Virtual terminal services are defined under ISO 9040[3] and virtual terminal protocols are defined under ISO 9041.[4]
