7.4Keypad Driver/Hardware Window Manager

7.4.1Function

The keypad driver (KEYPAD.EXE) is used to add the keypad function to the system. Application programs can use the keypad by calling the keypad driver functions via the keypad library (refer to Chapter 8.6.3 “Keypad Library”).

This keypad driver internally calls the hardware window manager that enables the use of the hardware window. Therefore, the use of the keypad driver requires the residence of the hardware window manager. The keypad driver is also used by some utilities (refer to Chapter 9 “Utility”.) supported for this terminal. Therefore, before executing an application program or utility that uses the keypad driver, make it reside in the main memory.

The relationship between the keypad driver/hardware window manager and application programs is shown by the following diagram.
