+;*	attach	- current owner of device
+;*		  if 0, no owner
+;*		  if 0ffffh, a mimic device
+;*	queue	- linked list of PDs waiting to attach
+;*	flag	- run-time flags
+;*	startcol- used for line editing
+;*	column	- used for line editing
+;*	nchar	- 1 character read ahead for CTRL chars.
+;*	mimic	- cio dev that mimics us.
+;*		  0ffh means no mimic device
+;*	msource	- if attach = 0ffffh, we are a
+;*		  mimic device and msource is the
+;*		  device we are mimicing.
+;*	pc	- physical console number
+;*      vc	- virtual console number
+;*	btmp	- temporary line editing variable
+;*	rsvd	- unused
+;*	state	- current state of virtual console
+;*	maxbufsiz - maximum file size for buffered mode
+;*	vinq 	- address of QPB for this virtual console's
+;*		  input.  written by PIN, created by the VOUT
+;*		  process associated with this virtual console
+;*	voutq 	- address of QPB for this virtual console's
+
+;*		  output. written and created by the assoc. VOUT
+;*	vcmxq	- MX queue for changing of virtual console state
+;*      qpbflags- the 1st 8 bytes of a Queue Parameter Block, for
+;*		  queue reads and writes, used only by reentrant
+;*                intercept code
+;*	qbuff	- buffer for queue writes
+;*	cosleep	- temporary list for processes waiting for XIOS console output
+;*	usleep	- user process sleeps here
