Serial Programming
Commands
The serial programming commands can be used in place of the programming
bar codes. Both the serial commands and the programming bar codes will pro-
gram the NCR RealScan 7837 High-Performance Scanner. For complete
descriptions and examples of each serial programming command, refer to the
corresponding programming bar code in this manual.
The device must be set to an RS-232 interface (see page 1-6). The following
commands can be sent via a PC com port using terminal emulation software.
