Filed: 1989-10-04
Abstract: PURPOSE:To abort a document in an opposite terminal equipment reception memory sent till the point of time of transmission of a command by sending a document abort command to a communication abnormal end command from a control panel section during transfer of a document. CONSTITUTION:Upon the receipt of a forced interrupt command from a document transfer user, a control panel section 1 recognizes the command to be an interrupt command from the user and informs the reception to an expansion communication control section 6. The expansion communication control section 6 discriminates whether the document is to be aborted or not by the abnormal end command from the control panel section 1 and sends a document abort command in the case of the document abort and sends a session stop command after the reply is awaited. Thus, all coded data till the transmission of session stop command in the reception memory of the opposite terminal equipment are aborted when the user mistakes the destination.
