/*****  REGISTRY USAGE

	AppleTalk port information is kept in the registry using the
	registry API of Win32.  The monitor is installed by creating
	a registry key, "AppleTalk Printers" at

	HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Monitors

	This key is refered to as the AppleTalk Monitor root key.  Two
	subkey of this root key are created.  "Options" contains registry
	values for configuration options for the monitor on a global
	scale, and "Ports" contains subkeys for each AppleTalk printer
	defined.

	The name of the port subkey is the port name for the printer
	as viewed in the NT Print Manager port list.  This key contains
	a number of values describing the port, including:

	REG_DWORD: TimeOut	  Number of miliseconds to wait for writes to
							the printer to complete

	REG_DWORD: ConfigFlags  Set of flags describing configuration of the
							port.  Currently only includes the flag
							indicating the printer is captured.

	REG_BINARY: NBP Name	NBP name of the printer as an NBP_NAME structure

	The "Options" subkey contains a number of registry values, including:

	REG_DWORD: DebugLevel
	REG_DWORD: DebugSystems
	REG_SZ: LogFile
