What is TTY/TDD

This chapter introduces synchronous, one-on-one, computer mediated communication. A discussion then is presented on the growth of typewritten, synchronous communication, beginning with the Tele- Typewriter/Telecommunications Device for the Deaf (TTY/TDD), and how instant messaging (IM) can benefit those who are deaf, and also others who wish to communicate rapidly without the use of a telephone or face-to-face (f2f) communication. Besides discussing benefits of synchronous, text-based, one-on-one communication, this chapter will also address the downfall to the written communication caused by the overuse of abbreviations and emoticons that is coming into regular use outside of the IM environment. After the author examines the pros and cons of CMC via IM, implications of the growth of CMC via IM are considered.
