The Debug_Query message directs the virtual device to enable its debugging
commands (if nay). 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.
 
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.
