UNIVERSAL TINIDF - Definitions for TTYINI

COMMENT \

TTYINI.NET-BIN File format:

Page 0:
	Word 0:  TTYINI version number of file (VERSION).
	Word 1:  Size of blocks in TTYINI entries (BLKSIZ).
	Words 2-511:  Net pointers, indexed by net number.  Each pointer
		      points to a page (called a NET page) in the file.
		      A word of all ones is a null pointer (symbolic address
		      NETADR).

NET pages (mapped at NETPAG):
	Words 0-511:  Host pointers, indexed by host number.  These pointers
		      point to the TTYINI data for each host, and are page 
		      numbers (HOST pages).  A word of all ones is a null
		      pointer (symbolic address NETPGA).  If not -1 but the
		      left half is nonzero then this is a pointer to another
		      host.

HOST pages (mapped at HSTPAG):
	Word 0:  Number of TTYINI blocks for this host (number of lines on 
	         host, symbolic name NUMTTY).
	Words 1-end:  TTYINI blocks (TTYBLK).

TTYINI blocks:

Each line has an associated terminal block of the following format:

TYPE
    ttynumber = RECORD (* TTYNumber *)
		    NetNumber,
		    HostNumber:  9bit integer unsigned;
		    LineNumber:  short integer unsigned; 
		END (* TTYNumber is a word of net, host,, line number *)
    directiontype = (toleft, toright, acrossglass, facing, 
		     diagonally-opposite, behind, acrosspartition, unused);
		    (* For fing/neighbor *)
    locationtype =  (ceras105, ceraslobby, cerasother, terman104,
		     termanother, termanlobby, dialin, gandalf, ethernvt,
		     arpanvt, decnvt, internetnvt, pty, erl206, meyer,
		     larkin);	    (* Typical locations *)
    flagtype =      (consultant, assignable, overhead, formfeed, lowercase,
		     tabs, pagepause, commandpause, raise, flag);
    tty = RECORD (* Tty *)
	      ttytype,		    (* Terminal type number, or -1 if ? *)
	      defttytype,	    (* Default type number or -1 if ? *)
	      length,		    (* Terminal length or -1 if ? *)
	      width:     integer;   (* Terminal width or -1 if ? *)
				    (* Total 4 wds *)
	      address:   PACKED ARRAY[1..30] OF char;
				    (* String for finger.  6 wds *)
	      location:  locationtype;  (* Where it is for finger.  1 wd *)
	      neighbors: PACKED ARRAY [directiontype] OF ttynumber;
				    (* For FINGER/NEIGHBORS.   8 wds *)
	      dplxmode:  (fullduplex, noduplex, halfduplex, linehduplex);
				    (* 1 wd *)
	      bits:     PACKED SET OF flagtype;
				    (* Bits.  2 wds currently *)
	      print-node: PACKED ARRAY [1..10] OF char;
				    (* 6 letter DECnet node name.  2 wds *)
	  END  (* Tty *)	(* 24 words, currently *)
