A keyboard has key positions providable with keys. A number of the key positions are actually provided with keys, whereas at least one other key position has a mode setting option. The mode setting option provides a feature that is readable by a microprocessor connected to the keyboard. Such features include pulse dialing parameters such as a pulse rate, a pulse width, and a pulse pause, or tone dialing parameters, or the like.
