Kermit

A terminal program and open, file transfer protocol (FTP) available for use on a variety of computers, from PCs to mainframes.

Kermit can be used to download files from a remote system to your home computer. It is distinguished by its ability to transfer files over Telnet and other connections that usually corrupt binary transfers, and it is often available as a Unix command.

Historical perspective: Kermit was developed at Columbia University and anybody can base their own program on it, but some Kermit software and source code is copyright by Columbia University.
