Abstract

PURPOSE:To put an online system in operation without altering a communication controller when a circuit terminating device is altered, by providing the communication controller with an automatic detecting function for a communication speed. CONSTITUTION:The processing control part 101 of the communication controller 100 sets a mark state in a transmitted data register and waits until a register 201 is placed in a data settable state. Once the register 201 becomes settable, said operation is repeated N times. Then, the elapsed time T of the operation is read out of a timer 102. The values T and N are reset and the communication speed is calculated. Consequently, when the circuit terminating device 300 is altered, the online system is put in operation without altering the device 300, so the system is altered at an actual spot.
