- : ZCPR-3 Terminal Capabilities (TCAP) Extended Definition
-
- as of 8 March 1989 (HFB)
-
- The ZCPR-3 TCAP is a 128-byte area positioned immediately after
- the Environment Descriptor. The configuration has been changed
- from the original descriptions contained in Richard Conn's book,
- ZCPR3, The Manual. The layout here is designed for backward
- compatibility with the original scheme while adding extensions
- to accomodate rudamentary business graphics and pull-down menus
- described in Dennis Wright's GRXLIB and portions of GRWLIB.
-
- Offsets mentioned in this description are from the base of the
- TCAP.
-
- Offset Item Description
-
- 0 Terminal Name 15 characters, alphanumeric. The first
- character must NOT be a space. A
- leading space means uninstalled TCAP.
-
- 15 Characteristics One byte indicating Terminal details as:
-
- B0 - 1 = Reverse or Intensify available
- 0 = Dim or reduced intensity avail
-
- B1 - 1 = Screen wraps on last col write
- 0 = No wrap if last column written
-
- B2 - 1 = Screen scrolls if last row/col
- position written
- 0 = Screen does NOT scroll if last
- col of last row written
-
- B3 - 1 = Term needs 10 secs on powerup
- 0 = Terminal instantly ready
- The following four bytes are for single-byte cursor movement
- codes FROM the terminal. If your terminal has no independant
- cursor movement keys, or implements cursor movement with multi-
- byte sequences, use any convenient single-key sequence you
- desire. The familiar WordStar "diamond" comprised of Control-E
- (Up), Control-X (Down), Control-D (Right) and Control-S (Left)
- is commonly used.
-
- 16 Cursor Up Cursor UP code from terminal (^E)
- 17 Cursor Dowm Cursor DOWN code from terminal (^X)
- 18 Cursor Right Cursor RIGHT code from terminal (^D)
- 19 Cursor Left Cursor LEFT code from terminal (^S)
-
- Some terminals need delays to perform certain functions. This
- may be more important as interface speeds increase. Delays are
- in milliseconds. Consult your terminal manual for the correct
- values to insert.
-
- 20 Clear Screen Delay in milliseconds (0 to 255)
- 21 Move Cursor Delay in milliseconds (0 to 255)
- 22 Clear to EOL Delay in milliseconds (0 to 255)
-
- Beginning at Offset 23 from the beginning of the TCAP, a
- sequence of Null-terminated strings define the Command Strings
- needed to make the Terminal respond as desired. If particular
- features are not implemented on nor needed by your terminal, a
- single Null (binary 0) disables that feature.
-
- Clear Screen (CL) - Clear Screen & Home Cursor
- Cursor Movement (CM) - Parsed string for cursor posi-
- tioning. See ZCPR3, The Manual
- for details. "%N" string added
- to send Binary 0 to Terminal
- Clear to End-of-Line (CE) - Clear from Cursor Position to
- the end of the current line.
- Cursor stays in current place
- Standout Begin (SO) - Enter Standout Mode
- If terminal uses DIM or Reduced
- intensity, the Initialization
- string (TI below) should set to
- reduced intensity, and this
- function sets normal intensity
-
- Standout End (SE) - End Standout mode
- If you use DIM or reduced
- intensity with normal for
- "Standout", this restores the
- DIM mode.
- Initialize Terminal (TI) - Initialize the terminal
- See notes for suggestions on
- DIM/Reduced Intensity above
- De-initialize Term (TE) - Restore Terminal to normal mode
- See above notes
- Delete Line (LD) - Delete line on which the cursor
- resides and move lines below it
- up by one
- Insert Line (LI) - Insert blank line before the one
- on which the cursor positioned,
- and move lines below down one.
- Cursor moves to beginning of
- the new blank line
- Clear to EOS (CD) - Clear screen from current cursor
- position to the End-of-Screen
- The following definitions implement portions of the GRXLIB and
- GRWLIB functionality, but in different TCAP locations.
-
- Graphics Delay - Delay for Graphics On/Off. Use
- greater of the two delay times
- in milliseconds. Values of 0 to
- 255 are acceptable
- Graphics Mode On (GO) - Set Terminal to Graphics Mode
- End Graphics Mode (GE) - Restore Terminal to normal
- Alphanumeric mode
- Cursor Off (CDO)- Disable Cursor display. Needed
- for Pull Down Menus
- Cursor On (CDE)- Enable Cursor display. Needed
- for Pull Down Menus
-
- Several graphics strings are needed to implement the desired
- level of functionality. Each of these is needed in the
- specified order. The terminal should first be placed in the
- graphics mode, then the desired string sent. If strings for
- all terminals are only a single character, this may be reduced
- to a character array in the future.
-
- Upper-Left Corner (GULC) - String for now
- Upper-Right Corner (GURC) - " " "
- Lower-Left Corner (GLLC) - " " "
- Lower-Right Corner (GLRC) - " " "
- Horizontal Line (GHL) - " " "
- Vertical Line (GVL) - " " "
- Solid (Full) Block (GFB) - " " "
- Hashed Block (GHB) - " " "
- Upper Intersect (GUI) - " " "
- Lower Intersect (GLI) - " " "
- Intersection (GIS) - " " "
- Right Intersect (GRTI) - " " "
- Left Intersect (GLTI) - " " "
-
- The remainder of the TCAP should be filled with binary Zeros to
- properly handle future additions.
