Is a terminal-automation software. You can access remote devices over telnet- and ssh2-protocol. It supports ASCII-, ANSI-, VT100- and xTerm-Terminals. The base-object of the THB-Terminal is the CfgEngine object, which has builtin support for login- and prompt- handling. So you don´t have to check for a login-prompt, for the cli-prompt or for the --more--prompt and so on.
