Customizing and Using MAI-OC › SCS Character Support

SCS Character Support

SCS control characters are used by some systems for print layout instructions. They tell an output device (usually a printer) how to respond to tab, spacing, line break and other formatting control sequences.

Not all SCS control characters can be fully simulated at a terminal; however, none cause a session to be rejected, and wherever possible MAI-OC translates the SCS character to the best equivalent function that OCS mode can provide.

This section details the actions taken by MAI-OC on receiving data streams containing the following SCS characters:

New Line X'15'

Data following the character is displayed on a new line of the operator window.
