摘要
This invention relates to a novel and way to use a twelve button telephone keypad for alphanumeric data entry. This invention also relates to a method of alphanumeric data entry using short duration or long duration binary key actuations using a simultaneous coding system and/or sequential coding system for communicating on a standard twelve key push-button telephone keypad. Two binary keys are used for an all capital letter mode or two binary keys for a lower-case letter mode, along with three binary keys for an upper-case letter mode, for producing full alphanumeric text, including punctuation, symbols and control.
