The 3190 Rear Customer Display (RCD) operates by converting recognized data, supplied by serial communication,
into a display message. The supplied data may also contain commands that control the display.
The 3190 RCD uses a limited command structure for display control, requiring minimal programming effort. The
table below lists the display control features of the 3190 RCD and control codes (in ASCII, DEC, and HEX
expression). The display control command structure, with examples, is described in this section.
