The Kermit Project, a program to create a transparent and flexible file transfer protocol, is begun at Columbia University.

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

Hayes Corporation (Previously D.C. Hayes Associates) releases the Hayes Smartmodem 300, which introduces the AT Command Set for Modems, which standardizes a language for interacting with modems. This language (with additions) is still in use today. The Hayes Smartmodem 300 is capable of dialing the phone and answering incoming calls, all without additional hardware and software.

This command set was created by Michael D. Eaton and applied for as a patent on March 3, 1980 (Issued June 7, 1983). The patent number was 4,387,440 and describes the command set in use to the present day. The rights for this command set were purchased by Hayes Corporation and are now known as the "Hayes Command Set".

The Original IBM PC (Personal Computer) is introduced.

       Has options for monochrome and CGA color display. Receives 
    generally good reviews and acceptance by business users and a few home
        users. Original DOS version 1.0 released which supported only
       single sided disks (160K capacity). Later version 1.1 corrected
       bugs (problems) in the DOS programming code and provided double
       sided disks (320K capacity), and faster disk access, date and
       time stamping and better serial communications.

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.
