Abstract
A communication system has a main device capable of communicating with a destination station through a line and at least one subsidiary device connectable to the main device. The main device includes an operating state signal transmitting system that transmits an operating state signal representing that the main device is currently performing a predetermined operation when the main device receives, from the subsidiary device, a communication request signal requesting a communication from the subsidiary device through the line, while the subsidiary device includes a first notifying system that notifies that the main device is performing the predetermined operation when the subsidiary device receives the operating state signal from the main device.
