Abstract
A system for communicating data between a computer and a unit remote from the computer is provided, comprising receiving input information from a user in the remote unit and for producing data signals corresponding to the input information, producing error corrected message signals from the data signals, generating acoustical tones corresponding to the error corrected message signals, communicating said acoustical tones over a first communications link, said first communications link being bi-directional so that the remote unit communicates data with the computer, and receiving acoustic tones over said first communications link from the computer, the acoustical tones being adjusted for the conditions of the first communication link prior to transmission to the remote unit. The remote unit may also receive data from the computer over a second communications link, which is independent of the first communications link so that the remote unit receives data from two different communications links. A system for communicating a plurality of different types of data between a user and a computer during a single data session is also provided.
