The ISO VT (Virtual Terminal or Video Terminal) service and protocol (VTP) allows a host application to control a terminal with screen and keyboard and similar devices like printers. In addition, VTP also supports the less common application-application and terminal-terminal communication.
VTP is comparable to Telnet in the TCP/IP suite but more powerful. VTP also includes control of cursor movement, colors, character sets and attributes, access rights, synchronization, multiple pages, facility negotiation, etc. This means that the huge number of classic terminal type definitions are unnecessary at each host in the network, as the VT protocol includes the corresponding commands for one abstract virtual terminal that only have to be converted by the local implementation to the actual terminal control sequences. Consequently, the use of VT means not every host needs to know every type of terminal.
The java applet included in this project supports connection to VT hosts.
