Scanner Direct IO Commands

The scanner supports a number of Direct IO commands that allow access to

the commands available on the interface which are not directly supported

by UPOS. Applications may utilize the Direct IO commands by accessing the

Direct IO Method (see the Unified POS Retail Peripheral Architecture, version 1.13

for details) with the appropriate arguments, as detailed below. For a com-

plete list of commands and implementation details, see DR90000351, Data-

logic UPOS DirectIO Commands (available at www.datalogic.com).
