This service is issued when a command is unknown.
Notes
This service is issued when a command is unknown, before the filing system is called to attempt to ‘run’ the command (See OS_FSControl 4).
NetFS uses this service to implement file server commands. Use the command table? in a Relocatable Module if possible to implement new *Commands.
