Device volume control in multimode computer systems |
摘要 |
A volume control handler allows users to dynamically alter the volume level of an audio device when the device is under control of a DOS mode application. The dynamic volume adjustment is performed without pausing or halting the DOS mode application. A system incorporating the volume control handler allows users of DOS mode applications to control a device's volume output in a manner similar to that provided by WINDOWS-compliant applications.
