PURPOSE:To improve the reliability of communication data by storing a text during line connection at an application level to a status queue memory and applying status transition processing while confirming the return from the opposite station so as to repeat the said operation until the state reaches finally to the line disconnecting state. CONSTITUTION:Text analysis/edition circuits 29, 31 copy a text during line connection to another idle buffer during the transmission/reception processing of a series of application levels, the result is fed to a transmission data queue memory 32, the packet copying the text is stored in a temporary status queue memory 35 and the transition processing of status of the text, that is, the transition processing of a packet status code 22 is executed. The status transmission processing is executed by a transmission processing table circuit 36 so as to repeat the storage to the status queue memory and status transition until the state reaches the line disconnecting state finally thereby enabling error check after the significance of data is recognized. |
