Abstract
A data communication system comprises a portable data processing terminal, such as an electronic notebook, and an external data processing apparatus, such as a personal computer. When the electronic notebook is connected to an RS232C I/F box connected to the personal computer, an I/F switch provided in the electronic notebook is switched on to supply a connection signal to an RS232C I/F circuit in the electronic notebook. An interruption signal is supplied from the RS232C I/F circuit to a CPU of the electronic notebook so that a communication program previously stored in a ROM is activated and a communication request is sent to the personal computer. The personal computer responds to the communication request sent from the electronic notebook and returns a response signal so that a data communication process is performed.
