Scanning Standard RS-232 activates the RS-232 driver but does not change port settings (for example, parity, data bits, and handshaking). Selecting another RS-232 host barcode changes these settings.
The CUTE host disables all parameter scanning, including Set Defaults. If you inadvertently select CUTE, scan Enable Parameter Barcode Scanning in the MP72 Scanner Scale Barcode Programming Guide, then change the host selection.
