Debug_Query

include vmm.inc

mov eax, Debug_Query

VMMcall System_Control


The Debug_Query message directs the virtual device to enable its debugging commands (if any). The virtual device should display a list of debugging commands, then read the debugging device for command input from the user. The system sends this message when the user enters a virtual-device command (a period followed by the name of the virtual device) at the WDEB386 prompt.

Parameters

This message has no parameters.

Return Value

The carry flag must be clear.

Comments

This message is intended to be used only in debugging versions of the virtual device. Support for this message should be removed from the final virtual device.
