- The Technology Assessment Program (TAP) is pleased to make this
- software available, free of charge, to encourage the use of ASCII,
- especially for communication between millions of hearing
- computer/modem owners and deaf and hard of hearing people who also
- have access to ASCII communication. This software, called ASCII-
- TDD, is the updated version of the former HAYESTDD software. Its
- new name better reflects the purpose of the software.
-
-
- TO RUN THIS SOFTWARE:
-
- To start ASCII-TDD, turn on the computer and boot up the operating
- system. After the system is up and running, switch to the "A" drive
- or whatever drive you plan to use to run the program. Put your disk
- in drive "A" and close the drive door. At the A> prompt, type
- ASCIITDD and press the "Enter" button on your keyboard. The program
- will load, and the simple commands for its use will appear on the
- bottom of the screen.
-
-
- TO HEARING USERS OF THE SOFTWARE:
-
- If you are a hearing person calling a deaf or hard of hearing
- person, this software will help. However, there are some things you
- should know:
-
- 1. You MAY need to inform the deaf or hard of hearing person that
- you are going to call in ASCII.
-
- A deaf person receiving a call has no way of knowing whether
- the incoming call is in ASCII or Baudot. Therefore it is up to
- the receiving device (the deaf person's TDD) to switch between
- ASCII and Baudot when a call comes in. MANY ASCII TDDs CANNOT
- DO THIS. Some have to be set manually to ASCII.
-
- A deaf person may use a Baudot TDD for everyday conversation
- but may also have a computer and modem. Using this software,
- you can talk to the deaf person through his or her computer
- modem; but the deaf person will have to make arrangements to
- have the computer answer the phone instead of the TDD.
-
- Both of these situations mean that you may have to inform the
- deaf person that you will be calling in ASCII. (Some deaf and
- hard of hearing TDD users do have products that can
- automatically switch between Baudot and ASCII, but these are
- a minority.) This is an unfortunate situation, but one that
- will not change in the immediate future.
-
- You can reach the deaf person by calling a relay service and
- having the service contact the deaf person, so that you can
- inform the person you will call back in ASCII. Or, if fax
- machines are available, it may be possible to send a fax to
- the person. Once you have informed the deaf person that you
- will call in ASCII, you can then have a completely private
- conversation using this software.
-
- 2. If the deaf or hard of hearing person has a Hayes-compatible
- modem and an IBM-compatible computer, it may be helpful to
- send the person a copy of this software to use for
- communicating with you.
-
- 3. It is necessary to give a "GO AHEAD" signal to the person at
- the other end of the line. When you are finished typing, type
- "GA". It signals the other person to start typing. "SK" means
- "STOP KEYING." It indicates that the conversation is at an
- end. Both parties conclude with goodbyes and "SK" before
- either one hangs up.
-
- 4. It is not necessary to use the TAB or ENTER key when typing
- since a TDD display only displays one line of type at a time.
-
-
- TO DEAF AND HARD OF HEARING USERS OF THE SOFTWARE:
-
- If you are calling a hearing person with a computer and modem, this
- software will help. However, there are some things you should know:
-
- 1. You MAY need to inform the hearing person that you are going
- to call in ASCII.
-
- Most hearing people answer the telephone by voice. (Some phone
- lines are attached to computers and the computer answers the
- phone.) The hearing person may need to turn on the computer
- and have the computer answer the phone when you want to call.
-
- Therefore, you may need to inform the hearing person that you
- will call back using ASCII. You can call the hearing person by
- using a relay service and informing the person you will call
- back in ASCII. Or, if fax machines are available, it may also
- be possible to send a fax to the person. Once you have
- informed the hearing person that you will call in ASCII, you
- can then have a completely private conversation using this
- software.
-
- 2. If the hearing person has a Hayes-compatible modem and an
- IBM-compatible computer, it may be helpful to send the person
- a copy of this software to use for communicating with you.
-
- 3. It is not necessary to use the TAB or ENTER key when typing
- since a TDD display only displays one line of type at a time.

- PROBLEMS OF BAUDOT and ASCII:
-
- In the early 1960s, AT&T switched from teletype equipment to
- computers. It gave its old teletypes to deaf people for use as
- telephone communication devices. These teletypes became the basis
- for the modern Telecommunications Device for the Deaf (TDD) system
- used by deaf and hard of hearing people. Today there are hundreds
- of thousands of TDDs in use in this country.
-
- The old teletype equipment and the newer TDDs are based on the
- Baudot code. This code uses five binary bits to symbolize each
- character. Computers use a seven-bit code called ASCII or an
- eight-bit code called extended ASCII. Baudot and ASCII codes are
- not compatible.
-
- Some of the newer TDDs can communicate in either Baudot or ASCII
- code. Many people purchase these TDDs and expect to be able to
- communicate in ASCII with a friend who has a home computer and
- modem. Unfortunately, almost all communication software for
- computers is designed for person-to-computer communication, such as
- when a computer bulletin board is called. There is little emphasis
- on person-to-person communication.
-
-
- FOR MORE INFORMATION AND TO GIVE US FEEDBACK:
-
- The Technology Assessment Program would appreciate your comments
- and suggestions about this software and about how direct
- communications between computer users and TDD users can be
- improved.
-
- The TAP now offers a bulletin board system (BBS) for users of this
- software. The BBS features updates of the software, and the author
- of the software will answer your questions. The bulletin board will
- continue for as long as our resources allow. CALL (202) 544-3613
- [2400 Baud, ANSI terminal emulation] to reach our BBS, or you can
- give us feedback by writing to us at Gallaudet University, 800
- Florida Avenue, N.E., MSSD 200, Washington, DC 20002.
