Abstract

To provide a method for controlling a transmission system with quick response in which plural electronic devices are connected to one host apparatus through a common data line. The method for controlling the transmission system of the present invention comprises: a step of transmitting a command signal for releasing the data line and suspending the processing through a command signal line to the electronic device occupying the data line in the state where one of the plural electronic devices is executing the processing that occupies the data line so as to make the electronic device release the data line and suspend the processing and to perform data transmission between the host apparatus and the other one of the electronic devices; and a step of resuming the suspended processing after the data transmission between the host apparatus and the other electronic device.
