ON-LINE BARCODE PRINTER WITH AUTOMATIC COMMUNICATION PARAMETER DETERMINING SYSTEM

摘要

An on-line barcode printer (10) is shown for communicating with one of a number of host computers (12) having various communication parameters. The barcode printer automatically determines the communication parameters of the host computer coupled thereto in order to initialize an UART (28) of the printer so as to eliminate the need for manual initialization thereof. The communication parameters automatically determined include baud rate, parity, the number of data bits and the number of stop bits.
