 The SET TERMINAL (abbreviated SE TE) command identifies to EDT the type
 of terminal you are using.  Normally, EDT will set the terminal type by
 asking the operating system what type it is.  If it does not appear to
 have set the type correctly, you can use the SHOW TERMINAL command to
 see what EDT thinks your terminal is and the SET TERMINAL command to
 correct it if necessary.  If your terminal is not a VT100 or a VT52, it
 should be set to HCPY (hardcopy).

1  –  HCPY

 HCPY stands for hardcopy.  EDT considers a terminal hardcopy if it is
 not a VT100 or a VT52.  On such terminals change mode does not use the
 screen as a window onto your buffer, but instead shows you the current
 line with the cursor position indicated.  You type NOKEYPAD commands and
 EDT will keep you informed by printing the current line after each
 command.

2  –  VT100

 The VT100 is a family of terminals, all based on the original VT100
 terminal. This class of terminals includes the VT101, VT102, VT125,
 VT131 and VT132.

3  –  VT52

 The VT52 terminal is the predecessor of the VT100 family.  It does not
 have reverse video, and has fewer keys in its keypad.

4  –  SCROLL

 This option indicates that your terminal has scrolling regions and EDT
 may use them.  This is the default for most VT100 terminals.

5  –  NOSCROLL

 This option indicates that either your terminal does not have scrolling
 regions or EDT should not use them.  This is the default for VT52
 terminals.

6  –  EDIT

 This option indicates that your terminal has the screen editing features
 of the VT102.  These are IL (insert line), DL (delete line), ICM (insert
 character mode) and DCH (delete characters).

7  –  NOEDIT

 This option indicates that your terminal does not have the screen
 editing features of the VT102.

8  –  EIGHTBIT

 This option indicates that your terminal contains the DEC Multinational
 Character Set, which extends ASCII to include letters with diacritical
 marks and other characters used in Europe.

9  –  NOEIGHTBIT

 This option indicates that your terminal does not contain the DEC
 Multinational character set.  On such a terminal characters which cannot
 be displayed directly are displayed using <>.
