Abstract:
An audiographic telephone conferencing system between a plurality of parties or users either directly connected or through a piece of apparatus known as a "meet me bridge" over voice grade telephone lines. Each user has a programmed personal computer which controls a programmable or "smart" modem, cassette recorder/player, and speakerphone. A protocol is implemented by the software, i. e. the computer program, in each of the computers which puts its respective modem in a listening mode to monitor the phone line at all times. The computer is further programmed and includes a memory for storing and transmitting graphics presently on hand to other user(s) via the modem during a teleconference or alternatively receive graphics from another user, or it can switch to an external graphics program to make new or modify existing graphic images. However, one is unable to speak on the telephone line while a graphic is being transmitted during a teleconference due to the fact that voice alternates with graphic transmissions.
