CONCEPT
TELNET enables the establishment of a connection to a remote system in such a way that the local terminal appears to be a terminal at the remote system.
NETWORK VIRTUAL TERMINAL
Via a universal interface called the Network Virtual Terminal (NVT) character set, the TELNET client translates characters (data or commands) that come from the local terminal into NVT form and delivers them to the network. The TELNET server translates data and commands from NVT form into the form acceptable by the remote computer.
EMBEDDING
The same connection is used by TELNET for sending both data and control characters. TELNET accomplishes this by embedding the control characters in the data stream.
