ABSTRACT:
The system unit of an IBM compatible personal computer generates a distinctive audible "Beep" signal from the system unit's own sound transducer in response to the successful decode of a barcode label in a keyboard emulation data collection device such as a barcode reader. To initiate the generation of such a Beep by the system unit, the keyboard emulation system simulates a benign error condition which does not affect the operation of any application programs resident in the system unit and which does not require any modifications to the operating system or any special device drivers for its proper operation. The successful collection of encoded character data and transmission of that data to the keyboard port of a host computer by a relatively unsophisticated operator is further enhanced by built-in logic for reliably and simply deducing which keyboard communication protocol from several candidates is currently in use and for deducing the status of the computer's Caps Lock flag by eliciting a Reset Status Indicators command from the system unit. If the Caps Lock flag is in its shifted state, all case sensitive data is automatically transposed so that it will be correctly interpreted.
