 The User Mode Diagnostics provide a means for the system manager
 to perform sanity checks and other tests of the system's peripheral
 hardware.
 
 UMDs are available for the following DIGITAL devices:

	RP04, RP05, RP06	RF11		RK05
	RK06, RK07		RS03, RS04	TU56
	RP02, RPR02, RP03	TU16, TU45	TU10, TS03
	TERMINALS
 
 Devices to be tested should be allocated to the terminal initiating
 the test.  Disk packs or tapes on a tested drive are overwritten.
 
 The following is an example of initiating a user mode diagnostic.
 
	>ALL DM1:
	>RUN $RK06
 
	START RK06 DIAGNOSTIC - TIME OF DAY=hour:minute:second
 
	DEVICE?  DM1
	  **WARNING** DM1: RESIDENT DATA WILL BE DESTROYED **WARNING**
	CONTINUE?  Y		(N or RETURN aborts diagnostic)
	FORMAT DISK ONLY?	(N intiates customer-mode sequence)
				(Y formats disk and exits)
 
	   or
 
	CONTINUE?  SERVICE	(N or RETURN aborts diagnostic)
	TEST PARAMETERS (OCTAL) = nnnnnn
	CONSOLE SWITCH FOR INTERVENTION (DECIMAL) = n
 
 In either case, the diagnostic can be aborted by:
 
	^C
	MCR>ABORT
 
 To obtain more information about a particular diagnostic see 
 the RSX-11M User Mode Diagnostics Reference Manual.
