SOLUTION: A user moves a mouse cursor displayed in the form of a comment mark 70 to the desired place to attach the comment and clicks a mouse 30 there. Thus, the position of the comment mark 70 is fixed and the position to attach the comment is designated. When the input of this comment attaching position is received, a comment attaching system respectively stores the number of order of the comment, the window ID of a window attached to a position information storage area, and the coordinate on the window in a comment number storage area inside a comment data storage area. When the position designation of the comment mark 70 is completed, a comment window 80 linked with that comment mark 70 through a straight line 71 is displayed on a display 40.

摘要： PROBLEM TO BE SOLVED: To provide a method for recognizing whether a communication opposite party supports a multiplex processing or not, by negotiating whether or not the multiplex processing is to be executed when a stream is newly generated with the same communication opposite party, monitoring whether or not a data repeater normally operates and periodically collecting a repeating packet communication delay situation and the like. SOLUTION: A voice data repeating installation (GW) is connected to a connection point between an Internet 101 and a public telephone network 102, a controller 104 is connected to the Internet 101 and a telephone set 105 or a communication terminal 106 is connected to the public telephone network 102. When the telephone set 105 makes accesses to a telephone set connection processing part from the public telephone network 102, it obtains the telephone number of a communication opposite party. When it receives a call termination notice from the telephone set 105, it terminates a busy repeating processing and cuts the connection. When a retrieval part receives a call repeating request, it retrieves address information of GW accommodating the terminal of the call opposite party form the telephone number of the opposite telephone set 105 which is included in the request.

摘要： PURPOSE: To perform information communication with an opposite terminal even when the name and address of the opposite terminal are unknown by providing a processing means for connecting the usable opposite terminal through a communication network with the information input other than the address of the opposite terminal for which connection is to be requested. CONSTITUTION: Respective drivers 190 and 200 analyze input from the keyboard and mouse 120 and 130 of a personal computer terminal 110 connected to the communication network 160 and transmits it to a CPU 250. The CPU 250 executes the storage program of a main memory 240 and reads and writes data such as a telephone, name and personal computer correspondence chart (TT) or the like stored in a disk device 260 beforehand. When a user inputs an opposite party telephone number and the name, the CPU 250 retrieves the TT of the device 260 and displays the address of the personal computer whose using possibility of the opposite party is high and the other information at a display 140. When an instruction is issued while viewing the display, the CPU 250 performs a connection processing with the opposite terminal through a communication I/F 270. Thus, even when the address of the opposite party is unknown, the opposite terminal is connected and the information communication is made possible.
