A technique is described whereby diagnostics analysis of functional problems, occurring in computing devices located at remote locations, can be analyzed without the need for relatively high bandwidth communications equipment, such as modems. The concept describes how touch- tone telephone lines for encoder/decoder communications can be used in the interpretation of commands and responses associated with the analysis. Typically, whenever hardware or software failures occur in computing devices, such as personal computers, micro-devices controlling printers, engines, appliances, etc., it is common practice to exercise a diagnostic program in an effort to pin-point the source of the problem, so that corrective action may be taken.
