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.
A communication device, comprising:
The communication device of 19, wherein the memory comprises a service store memory location that associates each software application of the plurality of software applications with a keyboard mode that is detected by the keyboard mode control software module to determine whether the generated keyboard output signals are converted into character codes or telephony tone signals.
The communication device of 18, further comprising:
The communication device of 18, wherein the telephone tone signals are Dual Tone Multi Frequency (DTMP) signals.
The communication device of 18, wherein the character codes are American Standard Code for Information Interchange (ASCII) character codes.
A method of controlling an operational mode of a communication device, comprising:
