PURPOSE:To shorten the time from the generation of a fault up to the restart of a computer system by holding the connected state of a terminal by communication procedure within an allowable range when opened service is interrupted by system stop due to the accidental fault of the computer system or its emergency maintenance work. CONSTITUTION:When the stop of a computer system due to the accidental fault or emergency maintenance work of the computer system is confirmed by a communication control monitoring means 121 in a communication controller 120, the holding of the service state or the holding of the connecting state in a communication state table 123 is recorded in an opposite terminal 129 recorded in the table 123 as connection completion or connection. In order to hold the connection state or the state in connection within the permitted range of the communication procedure corresponding to a line sort indicated by a connection circuit name 125, a connection state holding command is generated to a connection/reconnection control means 122. |
