Abstract
A barcode communication interface system and method capable of transmitting to a host computer barcode information received from a barcode decoder that is properly formatted and decoded without any error in an asynchronous manner. In this interface system, a microcontroller receives properly formatted barcode information data from the barcode decoder, converts the barcode information data into serial data through the asynchronous communication controller, and transmits this data to the host computer through an inverting line driver (ICL-232) and serial communication interface (RS-232C). The interface system of the present invention is compatible with various types of barcode readers, and enables the RS-232C serial communication interface to be driven by the power source for the barcode decoder.
