Net::Telnet - interact with TELNET port or other TCP ports

Net::Telnet allows you to make client connections to a TCP port and do network
I/O, especially to a port using the TELNET protocol. Simple I/O methods such
as print, get, and getline are provided. More sophisticated interactive
features are provided because connecting to a TELNET port ultimately means
communicating with a program designed for human interaction. These interactive
features include the ability to specify a time-out and to wait for patterns to
appear in the input stream, such as the prompt from a shell.
