From the doc: 'This program runs in console mode, at the Windows command prompt. Using the Telnet protocol in a special way, it allows the user to send commands to remote machines (hosts, hubs, routers, switches,...). So it can be used in batch, command files, etc. A script file (SCR extension) contains the instructions to establish the connection and the commands to be remotely executed. It has been tested under Windows NT to access various hubs, routers and hosts.'
