<p>PURPOSE:To contain plural data of the same code with a delimiter in a packet and transmit by providing a timer that starts operation on receiving the delimiter and resetting recognition of the delimiter in this time of operation. CONSTITUTION:When the number of received data is judged as less than 256 bytes, and the received data are not delimiter, operation of a packeting timer that watches overall time T1 is started. If data are received again within time t1, the timer is reset. When the next data is not received after lapse of time T1, received data up to that time are packeted. On the other hand, newly received data is a delimiter or the same code with the delimiter, operation of a delimiter judging time of time T2 (T2<T1) is started. If the next data are not received after lapse of time T2, the received data at this time are recognized as a true delimiter. When new data is received within time T2, the timer is reset. That is, the received data is recognized as ordinary data of the same code with the delimiter.</p> |
