;                      TS-802H
;                      ALL TERMINALS
;
;
; This program will load the function keys of any of the above 
; listed terminals and systems. All that is neccesary is to add
; the escape code that you desire. All escape codes listed in the
; user manuals will work with no problem.

; Insert your particular escape code here. Put it in the form
; of DB just as if you were inserting an actual message. This 
; data will be sent to the terminal the same as any ASCII string.
; The following is an example of the escape code sequence for
; loading the function keys.
;
; 	DB	ESC,'|11TEST',CR,CNTLY
;
; This will program key F1 to print TEST (with carriage return) locally
; and to the system processor.
; Refer to your users manual for a complete list of codes. 
;
;
;                      ON SCREEN LABELS
;
;
; If you wish to incorporate labels for your function keys insert
; the 'labels' in place of XXXXX in the code below. This code will
; setup the user line and line 24. Line 24 will be locked out, 
; therefore it will reduce your terminal to 23 x 80. If you do not
; want the labels simply insert ';' in column 1.
