Chapter 7: Programming 7-47
RS-232 Terminator Byte
The RS-232 Terminator Byte programming mode controls the use of
terminator bytes. If you use an RS-232 Terminator Byte, it goes at the
end of the message sent to the host terminal. If you included a BCC, it
follows the Terminator Byte and includes the Terminator Byte in the
calculation.
When you apply power to an NCR 7875-2000, the reset function checks
the RS-232 Communications Terminator Byte programming. If the
selection is Disable, it is ignored and an ETX (03) is automatically sent
with each message. If you select Enable, the ASCII code you
programmed is sent.

Terminator Byte Disable
ASCII Code 03
Specific Program Parameters
Terminator Byte
The Terminator Byte parameter contains two selections: Disable and
Enable. Scan the Hex 0 tag to disable the Terminator Byte, or the Hex 1
tag to enable it. The default is Disable.
ASCII Code
The ASCII Code parameter permits you to specify what ASCII code to
use for the Terminator Byte. Enter your selection by scanning the
appropriate two Hex tags (shown in the
ASCII Code Chart
). You can
select any value from 01 through 7F; however, the recommendation is
that you use the End Text (ETX) ASCII Code which is 03 Hex or
Carriage Return (CR) which is 0D. Scan the two appropriate Hex tags
