TELNET control information

As said in RFC 854:

A TELNET connection is a Transmission Control Protocol (TCP)
connection used to transmit data with interspersed TELNET control
information.

So, what's the TELNET control information? Can you get an example?

Solution

  • Control information is sent using sequences beginning with the IAC code. See the section titled TELNET COMMAND STRUCTURE in the RFC.
