Terminal capabilities entries
The terminal capabilities section of a terminal entry contains fields that tell OpenEdge features of the terminal being used. These entries are indented from the name line to distinguish them from the terminal name.
Terminal capabilities entries control visual attributes of the terminal: how big the terminal screen is, how to move to any point on the screen, how to refresh the screen, how to enter/exit special display modes (reverse, blinking, underline), etc. They also control specific terminal functions to set up and clean up the terminal properly, so as not to leave a terminal in an unexpected state (which might leave the terminal unusable).
These entries are the core sequences that OpenEdge uses to communicate with the terminal. Changing them can cause very unpredictable results and might even cause OpenEdge to put the terminal in an unusable state. The entries can be changed, but exercise great care in doing so.
Terminal capability entries consist of:
*A two-character mnemonic that identifies a generic terminal capability
*An assignment operator equal sign (=), or a pound sign (#)
*For certain capability types, a value that allows OpenEdge to understand and interact with the capability on a specific terminal
For example:
* Functional listing of terminal capabilities
