    • Each terminal (30, 60) in a full-duplex communication system comprises a computer-controlled display screen such as a CRT (62, 32), at least one input means such as a keyboard (64, 34), a mouse (36, 66) or a light pen (38, 68) and bidirectional communication means (40, 70) through which the terminals (30, 60) are interconnected. Each communication means comprises a receiver (78, 48) for receiving display information received at the terminal from the remote terminal(s) and a transmitter (46, 76) for transmitting information to the remote terminal(s) where it is displayed. In accordance with the invention, each terminal also comprises control (50, 180) which periodically reads its input means and communications means and uses the information contained therein to control the content of its display. Further, the control means at each terminal also provides to its transmitter instructions (figure 3) which are transmitted to the remote terminal to change the display at the remote terminal so that all the displays are the same. As a result of this arrangement, changes in the display that are made at the same time by the user at the local terminal and by the user at the remote terminal are entered on the display screens at both terminals at substantially the same time so far as is discernable by the users. As a result, not only can each user interact with the display but it is also possible for each user to interact with the other users through the display without having to wait for one user to complete his entry of information as in the prior art. As a result, truly interactive communication is possible through the display.

    •  外部のコンピュータを用いることなく設定可能な電話アダプタを提供する。IP電話アダプタ(1)の処理部(11)は、電話機(4)が接続されると、変換部(14)へダイヤルトーン(発信音)の音声データを出力して、IP電話アダプタ(1)における設定操作の項目を示すメニュー画面を表示する表示指令を、PC(5)及び表示部(13)へ出力し、識別部(15)からDTMF信号の所定の識別結果が入力されるまで待機する(S10~S30)。所定の識別結果が入力されると、入力された識別結果が、項目の確定に対応づけられた符号「#」であるか否かを判定し、符号「#」でない場合には、識別結果に応じた表示指令を表示部(13)及びPC(5)へ出力する一方、識別結果が符号「#」である場合には、確定した項目の処理を実行したのち、本処理を終了する(S30~S45)。
    • 提供了一种电话适配器,可以在不使用任何外部计算机的情况下进行设置。 IP电话适配器(1)的处理单元(11)当连接电话(4)时,输出到转换器(14)的拨号音(或中继线音)的语音数据,输出显示指令以显示 指示IP电话适配器(1)中的设置操作项目的菜单屏幕,PC(5)和显示单元(13),并且等待直到DTMF信号的预定识别结果从识别单元( (S10〜S30)。 处理单元(11)在输入了预定的识别结果时判定输入的识别结果是否是与项目确定相对应的代码“#”。 在判别结果不是代码“#”的情况下,处理单元(11)根据鉴别结果向显示单元(13)和PC(5)输出显示命令,但是在判别 结果是代码“#”,固定项目的处理,并结束程序(在S30到S45)。
