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 timeout and to wait for patterns to appear in the input stream, such as the prompt from a shell.
