Abstract

Abstract Transmission, speed at which data is transmitted over a digital transmission line between a transmission device and a remote device, is set by transmitting an inquiry command to the remote device at a predetermined transmission speed; receiving, from the remote device, a response to the inquiry command; determining based on the content of the response any transmission speeds common between the remote device and the transmission device; and setting transmission speed at which transmission between the transmission device and a remote device is to be performed to one of the transmission speeds common between the remote device and the transmission device.
