See full text

A transmitting/receiving unit performs a plurality of data transmission operations and data reception operations in parallel via a plurality of data communication lines. A mode selecting unit is used for a user to select one of a line specifying mode and a free-line searching mode. A line determining unit determines a transmission line from among the plurality of data communication lines, the transmission line being then used for performing a data transmission operation by the transmitting/receiving unit. The line determining unit determines the transmission line as being a line selected by a user from among the plurality of data communication lines when the line specifying mode is selected through the mode selecting unit. The line determining unit searches the plurality of data communication lines for a free one so as to determine the transmission line as being the free one when the free-line searching mode is selected through the mode selecting unit.
