Virtual Terminal




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,
# Allows remote log-on by local area network managers for the purpose of management,
# Allows users to Access Information from another host Processor for transaction processing,
# Serves as a backup Facility .

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.
