The difference between the scanner only and the scanner/scale format
is that the scanner/scale format has an address and a function code
following the optional Prefix Byte. For more detailed information on
message formats refer to the NCR Scanner/Scale Interface
Programmer's Guide (BD20-1074-A).
Beep at Scale Weight Transmission
This parameter allows the scanner to signal the transmission of a scale
weight that was requested by the host terminal. Scanning the Hex 9
tag activates this feature and causes the unit to sound a Good Read
tone as the weight information is sent to the terminal.
