---

A method of electronic external communication would be the telex system. It has features which are a lot similar to the fax e.g, message receivers are contacted over the telephone wire and a ‘ready to receive’ confirmation known as an ‘answer back code’ is confirmed by the receiving tele printer. Both fax and telex machines have a combined and linked system to tell one another that they are ready to communicate. Telex has various fax type facilities such as redialling busy numbers, logging and reporting on calls and sending telexes to multiple recipients. Users of telex machines can have either a dedicated telex terminal or a telex facility into a networked computer terminal. The advantage for now is that there are lots of telex machine users throughout the world, although the fax is a high competitor.

By using electronic text preparation and editing techniques, telex messages may be prepared, edited and checked prior to transmission by means of VDU or LCD display and microprocessor memory systems. Using features like those of fax receivers, such messages may be kept on electronic files until a later transmission time and the distributed automatically. After preparing the text of the telex, the user can make contact with the recipient by typing in the telex number, and then get feedback by an answer back code response. The telex is then despatched. Once it is delivered, the telex system resumes immediately a message acceptance mode, ready to receive incoming telexes, and will provide a series of print out message status reports.

Another method of electronic external communication would be using teletext on the television. By displaying visual text information on the television screen, anyone from around the world who has a compatible teletext television can access information about various things by just keying in numbers. Teletext is being overtaken by interactive television, which explains what is happening orally and in pictures.
