Abstract:
An apparatus and method for telephony tone signal and character code generation for QWERTY keyboards includes a QWERTY style keyboard, a processor and a keyboard mode control software module. The QWERTY style keyboard has a plurality of letter keys, wherein each letter key is configured to generate a unique input signal. The processor is coupled to the keyboard and is configured to convert each unique input signal generated by the letter keys into a character code and/or a telephony tone signal. The keyboard mode control software module operates on the processor, and controls whether the processor converts the unique input signals from the letter keys into character codes or telephony tone signals.
