The Disable_Global_Trapping service disables I/O port trapping for the
specified I/O port. This applies to every virtual machine.
 
This service must not be used unless an I/O callback procedure has been
installed for the given port using the Install_IO_Handler or
Install_Mult_IO_Handlers service during initialization.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────

           to be disabled.

Comments
 
The system applies to current global trapping state to each new virtual
machine as it is created. When the system first starts, global trapping is
enabled by default.
