TITLE	SEDTTY - COMBINED TERMINAL DEFINITION FILE FOR SED
SUBTTL	A CHRISTOPHER HALL FECIT

	SEARCH	SEDSYM
IFN TOPS10,<SEARCH UUOSYM>
IFE TOPS10,<SEARCH MONSYM>

;NOTE:  SEDTTY  combines  all  the terminal tables (which were formerly
;distributed separately) into one file. The tables  for  each  terminal
;can  be  enabled  individually by setting a flag below. If two or more
;terminals are enabled, code will also be set up which asks the monitor
;what type of terminal it is and/or processes  the  /Z:  terminal  name
;switch  (if  there's  only  one terminal type, no decisions have to be
;made, so that decision code does not assemble).

;CAVAET:  Most  of  the  tables  here  are  not up to date, some are of
;questionable reliability, and some define  different  arrangements  of
;SED commands on the keyboard. That is because many tables were sent to
;me  by  sites  who  had  those  terminals,  and I distribute them as I
;receive them. New tables or updates or  corrections  to  these  tables
;will be gratefully accepted and incorporated into this file. so PLEASE
;look  over the tables you want to enable to make sure they do what you
;want them to. The terminal tables,  not  the  documentation,  are  the
;final authority on which keystrokes invoke which commands.

;The only tables I can guarantee to be up-to-date are those for the DEC
;VT52 and VT100 family of terminals. I use those terminals every day.


;To add a new terminal:
;(see SED.MEM for a complete description of each table)

;1) Invent names for the terminal:
;     NAME5 (VT100) - 5-character (or less) name used to build labels
;     NAM4  (V100)  - 4-character name ditto
;     NM3   (V10)   - 3-character name ditto
;     TNAME (VT100) - Name to call the terminal. Used with the /Z: switch.
;		      This is the name returned by TRMOP. on TOPS-20,
;		      or set up in the T20NAM table [see below] on TOPS-20.

;2) Add a switch to the list below (format must be F'NAME5).

;3) Add "GOTERM('NAME5)" to the list at termnl (alphabetical is nice
;   but unnecessary).

;4) Add to CRTTAB: the SIXBIT terminal name (TNAME), under the switch
;   (F'NAME5).

;5) Add the terminal tables under feature test switch F'NAME5.

;6) If TOPS20, add TNAME to T20NAM: at the position of the index returned
;   from GTTYP (NOTE: The name in T20NAM must match name in CRTTAB in the
;   monitor).
;   NOTE: Every terminal must have an entry routine. The routine must begin
;   with the line "IFN ..IDX-1,<JRST DECIDE>" and end with "POPJ P,".

;NAMING CONVENTIONS:
;A number of labels or flags can be found in every terminal table. To avoid
;duplication, they should be named as described below. Similar labels not
;listed here should follow the same conventions. The intention is that if
;sedtty is assembled with all terminals on (all the F'NAME5==1), there will
;be no duplicate labels.

;O'NAME5	Address of terminal output table
;I'NAME5	Address of terminal input table
;C'NAME5	Address of routine to position cursor to given ROW, COLUMN
;L'NAME5	Address of routine to position to start of line
;E'NAME5	Address of entry routine
;X'NAME5	Address of exit routine
;S'NM3'.T	Address of terminal subtable (Example: SV52.T)
;S'NM3'.S	Length of terminal subtable (Example: SV52.S)
;F'NAM4'F	Fast-terminal flag (set if terminal sends XOFF-XON)
;F'NAM4'X	Some other terminal-dependent flag
