PURPOSE:To improve transmission efficiency by allowing data to by-pass a desired communication device by the control signal that is contained in the data itself. CONSTITUTION:A signal from a transmission line 3 is stored in a buffer shift register 13 through a receiver 10. A detecting circuit 18 monitors whether the data is a communication sentence addressed to its device or not, and opens a gate 16 when not to transmit the data to a transmission line 4. When the data is addressed to the device, the gate 16 is closed to prevent the data from being transmitted to another device, and whether the data is a skip command or not is distriminated. When not, this communication sentence is inputted. Further when so, a sequence controller 17 opens gates 32 and 34 for a time specified by a timer 30 to allow the command to bypass this device. |
