For example, kermit assumes an "unreliable" connection, and does it's own error-checking, while FTP relies to some extent on a transport layer that already has error-checking. I suppose they naturally have some similarities on the "outside" because they serve similar purposes, though. Anyway, kermit predates FTP by a few years. -- Pete Peter Turnbull Dept. of Computer Science University of York
