Abstract
A wireless mobile phone, is provided with a couple of buttons and complementary logic to facilitate entry and transmission of Morse code representations of alphanumeric data. As a result, a user may use the provided facilities to engage in non-verbal communication for sensitive subject matters in the middle of a call. In one embodiment, the complementary logic further facilitates echoing on a display, alphanumeric data corresponding to any entered Morse code representations. Additionally, each of the Morse code entry buttons includes one or more light emitting diodes (LEDs), and the LEDs are lit to visually echo the Morse code representations of any alphanumeric data entered through a standard input keypad.
