摘要: Mouse emulation includes two modes, a host mode in which the pointer behaves as of system and an emulating target being emulated. The display appears window within display. user can switch from to by clicking mouse key when is located also serves make input focus for receiving signals keyboard. depressing STOP key, keystroke need not be provided emulator because it would system's CPU. related data transferred through structure reserved memory space application does access, such BIOS area if IBM PC A driver provides standard responses service requests retrieves this structure, making hardware ports or software bypassing unnecessary.
