ことを特徴とするデータ通信装置。In a data communication device including a data terminal device, a modem, a network control device, and a power supply control device, when the data communication device receives a call from a partner station, the data communication device transmits a first call signal from the network control device to the power supply control device. When the power supply control device detects the first calling signal, it turns on the power of the modem, returns the first calling signal to the modem, and the powered-on modem outputs the first call signal to the modem. When a calling signal is detected, a second calling signal is output to the power supply control device and the data terminal device, and when the power supply control device confirms the first and second calling signals, it turns on the power of the data terminal device. Then, the data terminal device that has been powered on detects the second call signal and outputs a ready signal indicating that preparation for transmission/reception is complete to the modulation/demodulation device and the power supply control device to perform data communication. 2. A data communication device according to claim 1, wherein when the data terminal device is finished, the data terminal device turns off a ready signal and stops power supply from the power supply device.
