PURPOSE:To increase the communication speed and to attain the fast transfer of data by detecting the end of reception in case all characters received within a fixed period of time are equal to the specific data. CONSTITUTION:A DMA control means 2 transfers the data of variable length to a memory part 1 and the end of this data transfer is detected at every time the prescribed period of time is counted by a time counting means 3 which starts its counting action as soon as the transfer of data is started. Here a transfer end detecting means 4 detects the end of the data transfer when all characters received within a fixed period of time are equal to the specific data. |
