Abstract

PURPOSE:To inform the result of data abort due to an accident to the user by adding respectively a communication information element storage section, an abort data information detection section and a notice section each having a prescribed function to the adaptor. CONSTITUTION:When power of a G3 facsimile adaptor 3 is interrupted due to a fault such as power failure and is applied again, an abort data detection section 7 terminates the initialize processing of the system and checks a data flag. When no data flag is set, the system is initialized at this point of time. When the data flag is set, since it means that there is any data aborted without completing communication, communication information elements such as number of sheets transmission reception facsimile data and time for communication data storage are extracted from a talking information element storage section 6 and informed to the user via a notice section 8. After the notice, the data flag is reset and the initialization of the system is made complete.

[Problems to be Solved by the Invention] In the above conventional G3 facsimile adapter, after transmitting or receiving data is stored in the data storage section 10, the power supply of the G3 facsimile adapter 3A is turned off before executing the next communication process. If the power supply is disconnected due to the power plug falling off or a power outage, the stored data will be discarded due to the limited memory capacity that can be backed up, and even if the power is turned on again, the stored data will not be lost. Since the data cannot be reproduced, a situation where data is not delivered occurs. In this case, if the user's own station is the calling terminal, the user will judge that the communication is complete when the transmission data is accumulated from the G3 facsimile 2 to the G3 facsimile adapter 3A, and the user will judge that the communication is completed when the user's own station is the called terminal. In this case, the other station determines that the communication is complete when data is received and storage is completed, but the communication may not actually be complete, and the problem is that the user cannot recognize this. was. An object of the present invention is to provide a means for communicating the results of data disposal due to the above-mentioned accident to the user.
