ABSTRACT:
A portable computer, such as a laptop, notebook, or palmtop computer, comprises control routines for providing a sophisticated touch-tone dialer operable through an existing or supplied output speaker, enabling calls to be routed without making a wired direct connection between the telephone equipment and the computer. In one embodiment a system is provided for transmitting computer-usable data over a phone connection through a pre-stored relationship between DTMF tones and ASCII code.
