Template:Short description Script error: No such module "about".
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.
ISO Standards
Virtual terminal services are defined under ISO 9040[3] and virtual terminal protocols are defined under ISO 9041.[4]
