In a computer terminal an electronic device allows the selection of the terminal address and baud rate via a DIP switch (Dual In-Line Package) located internally in the terminal or via external selection means by allowing the setting of signal line voltage level by means of jumper wires in a communication connector. To enable the external option, predetermined pins in the communications connector are jumpered to disable the DIP switch, whose settings are then ignored. By jumpering other predetermined pins in the communications connector, the signal line levels define the terminal address and the terminal baud rate.
