	The LX8BIT handler is designed to be a serial line printer replacement
	for the LP handler under RT11-SJ, and can be installed with a
			COPY/SYS dev:LX8BIT.SAV name.SYS
	followed by a reboot.  I would suggest using a dummy 'name' to get
	the SET OPTIONS working before replacing your LP.SYS file.


	SET name	result					default
	-------		----------------------------------	-------

	WIDTH=DDD	columns/line, decimal			132
	CSR=000000	device RCSR address, octal		176500
	VECTOR=000	device RCSR vector, octal		300
	LENGTH=DD	lines/page, decimal			66
	NULLS=DD	decimal NULLS after CR, for padding	10
	TABS=DD		decimal spacing for soft tabs		8
			and for column counting (TRUN, WRAP)
			8 sets tabs at 9, 17, 25, etc.
    (NO)HANG		hang, or abort, for hardware errors	HANG
    (NO)EIGHT		eight-bit, or seven-bit			NOEIGHT
    (NO)LC		lower-case, or not			LC
    (NO)CTRL		pass control char's, or not		NOCTRL
			(includes null char.)
    (NO)TRUN		truncate lines greater than WIDTH,	TRUN
			but do not advance line.  See Wrap.

					printer generates
	CRLF		print CR	   LF after CR
	----		--------	-----------------
	    =00		   no			yes
	    =01		   no			no
	    =10		   yes			yes
	    =11		   yes			no		11

			hardware	wrap - lines wider
	TBWR		  tabs		than WIDTH force CRLF
	----		--------	---------------------
	    =00		   no			no
	    =01		   no			yes
	    =10		   yes			no		10
	    =11		   yes			yes

	FFB0		form-feed	print (block zero)
	----		---------	---------------------
	    =00		   no			no
	    =01		   no			yes
	    =10		   yes			no
	    =11		   yes			yes		11

		If no hardware FF, <CR, 6 LF's> substituted for FF.

	To operate in a 'pass-all' mode (7 or 8 bit), set OPTIONS:
	   NULLS=0  LC  CTRL  NOTRUN  CRLF=11  TBWR=10  FFB0=10
