The Kermit Project, a program to create a transparent and flexible file transfer protocol, is begun at Columbia University.WHAT IS KERMIT? Kermit is a file transfer protocol first developed at Columbia University in New York City in 1981 for the specific purpose of transferring text and binary files without errors between diverse types of computers over potentially hostile communication links, and it is a suite of communications software programs from the Kermit Project at Columbia University. The Kermit protocol and software are named after Kermit the Frog, star of the television series, The Muppet Show; the name Kermit is used by permission of Henson Associates, Inc. Over the years, the Kermit Project has grown into a worldwide cooperative nonprofit software development effort, headquartered at and coordinated from Columbia University. The Kermit Project is dedicated to production of cross-platform, long-lasting, standards-conformant, interoperable communications software, and is actively engaged in the standards process. Since its inception in 1981, the Kermit protocol has developed into a sophisticated and powerful tool for file transfer and management, incorporating, among other things: File group transmission File attribute transmission (size, date, permissions, etc) File name, record-format, and character-set conversion File collision options, including an "update" feature File transfer recovery Auto upload and download Client/Server operations Automatic per-file text/binary mode switching Recursive directory-tree transfer, even between unlike platforms Uniform services on serial and network connections An Internet Kermit Service Daemon (From the Kermit FAQ at Columbia)

Cynbe ru Taren writes Citadel BBS software for the Heath H89.From the Citadel.Org History: Citadel was born in December of 1981, when Cynbe ru Taren devised a new format of BBS software based on the concept of "rooms". Each room is essentially a message area, with the name of the room suggesting the topic of discussion within the room. One of the unique features of Citadel is that users can create their own rooms; thus, the Citadel grows larger because the users themselves become part of the construction crew. Cynbe wrote the first version of Citadel in ten days and ran it under CP/M on a 64k Heath H89, with the code, data and operating system all crammed into 48k of RAM. Today, Citadel is the most platform - independent BBS software available, with Unix versions flourishing on the Internet.
