ISO Virtual Terminal VT Services and Protocol VTP allows host applications to control a terminal that contains screens, keyboards, and similar devices, like printers, and the like. In addition, VTP also supports uncommon applications (Application-Application) communications and terminal-Tterminal communication.
VTP is more functional than Telnet in the TCP / IP protocol group. VTP also includes control features such as cursor movement, color, character set, and attributes, access, synchronization, multi-page, negotiation mechanism. This means that there is no need to define a large number of typical terminal types for each host in the network. If each abstract virtual terminal in the VT protocol has its corresponding command, this machine only needs to convert them to actual virtual in the implementation process. Control sequences. Therefore, through VT, it is not necessary to understand each terminal type per host.
