<p>PROBLEM TO BE SOLVED: To surely transmit data stored before power interruption and to be communicated to an opposite station even when the power of the storage type radio data communication terminal equipment(TE) is interrupted during the communication by the user and to restore the state of a power switch operated by the user after that. SOLUTION: When the user turns on a switch section 6 after the start of data transmission/reception, the OFF state of the switch section 6 is reserved in a data storage section 3. Then after the reception of a transmission confirmation message to a packet sent to the terminal equipment just before the switch section 6 is turned off, transmission data left in the data storage section 3 are sent to a DTE (external information processing unit) and an interrupt request message is sent to the terminal equipment. After the end of communication with the terminal equipment TE, a switch section 7 is interrupted by a control section 1.</p> |
