To understand scan code files, you must first understand the keyboard parameter file. When you press a key, you expect the operating system to perform some operation; for example, when you press the A key, you want a lowercase a to appear on your screen. The keyboard parameter file maps a keystroke to a particular operation. For a host session to recognize an operation, it is necessary to map the operation to terminal-specific scan codes. You may need up to three scan codes to represent a 3270 key operation.
If you configure CA Automation Point to emulate standard 3278 and 3279 terminals, CA Automation Point translates the scan codes for you. If you configure CA Automation Point to emulate other types of terminals (such as a 3279-2C terminal), you need to specify the appropriate scan code file. If CA Automation Point does not provide a specific scan code file for a particular non-3278/non-3279 terminal, you must create one for it.
