Devices and methods are presented to remotely dial wireless communications devices. A device is equipped with a microphone and a plurality of logic units to analyze incoming acoustic signals in the form of Morse code. Acoustic signals may comprise tapping sounds, or voice patterns to create the “dits” and “dahs” associated with Morse code. Background noise can be eliminated using digital signal processing (DSP). The device can be used in a variety of environments where phone numbers and addresses need to be dialed from a distance or in emergency situations. |
