Tektronix Terminals and Emulators
- Supported device
- Tektronix 4006/4010 storage-tube terminal; can be used with
emulators, but the options below take advantage of features not
present in the basic Tektronix terminal.
- GraphOn Corporation 200-series terminals. These emulate a
Tektronix-4010 with enhancements (selective erase, rectangle fill,
switch between Tek and VT100 modes).
- Digital Engineering, Inc., Retrographics modified VT100
- IRAF GTERM Tektronix terminal emulator, with color extensions.
- Xterm window on an X-window server. Emulates a Tektronix-4014,
with extensions (switch between Tek and VT100 windows).
- ZSTEM 240 and ZSTEM 4014 terminal emulators for the IBM PC and
clones. ZSTEM supports Tektronix 4014 emulation and the 4105 color
escape sequences. ZSTEM can be obtained from: KEA Systems Ltd.,
2150 West Broadway, Suite 412, Vancouver, British Columbia, Canada,
- Visual-603 and 630 terminals. These are VT100/220 compatible
terminals with Tektronix 4010/4014 emulation (Visual Technology
Incorporated, 1703 Middlesex Street, Lowell, Mass 01851). The
Visual 630 has the capability of displaying dual text and graphics.
This feature is not used in this driver. Graphics mode is entered
automatically when the graph is drawn but only exited when PGPAGE
or PGEND is called. Therefore, for multiple plots interspersed
with text I/O, use PGPAGE at the end of each plot. This will prompt
for a carriage return before switching. If this is not done,
intervening text will appear on the graphics screen. Graphics mode
can be entered and exited from the setup menu, or by SHIFT-PF1.
Graphics extensions include rectangle fill, selective erase and
switch between Tek and VT100 modes.
- IBM PC's and compatibles running MS-Kermit 3 as a terminal emulator.
The video board is assumed to have sufficient memory to retain the
graphics image in memory when switched to text. This will be true
for VGA and EGA, but some early PCs might not be able to do this.
If Kermit is using full VGA resolution (ie SET TERMINAL GRAPHICS
VGA), there is not usually enough memory to store the full 480
vertical lines, so the bottom few lines may disappear. Tektronix
enhancements include selective erase, colours, rectangle fill, and
switching between text and graphics mode. The cursor may be
operated with the mouse. Tested with Kermit version 3.1.
- Tektronix 4100 series color terminals (and emulators, e.g.,
Versaterm-PRO for Macintosh).
- Device type codes
- /TEK4010 Tektronix-4010 terminal
- /GF GraphOn terminal
- /RETRO Retrographics VT640 terminal
- /GTERM GTERM terminal emulator
- /XTERM XTERM terminal emulator
- /ZSTEM ZSTEM terminal emulator
- /V603 Visual V603 terminal
- /KRM3 Kermit 3 on IBM-PC
- /TK4100 Tektronix 4100 series terminals
- Default device name
- The logged-in terminal:
- Default view surface dimensions
- Depends on monitor; nominally 8in (horizontal) by 6in (vertical).
- A standard Tektronix terminal displays a screen of 1024 pixels
(horizontal) by 780 pixels (vertical), with a nominal resolution
of 130 pixels per inch. The actual resolution may be less.
- Color capability
- /TEK4010, /XTERM: none; only color index 1 is available; selective
erase is not possible. Requests to draw in color index 0 are
- /GF, /RETRO, /V603: color indices 0 (erase, black) and 1 (bright:
usually white, green or amber) are supported. It is not
possible to change color representation.
- /GTERM: color indices 0 to 15 are available and default to the
standard PGPLOT colors. The color representation can be changed.
- /ZSTEM: color indices 0 to 7 are available and default to the
indicated in the ZSTEM setup menu (which default to the standard
PGPLOT colors). The color representation cannot be changed.
- /KRM3: color indices 0 to 7 are the standard PGPLOT colors. Indices
8 to 14 are also available, but are BRIGHT versions of 1 to 7,
and thus non-standard. Color representation can't be changed.
- /TK4100: color indices 0-15.
- Input capability
- Depending on the emulation, the graphics cursor may be a pointer,
a small cross, or a crosshair across the entire screen. The user
positions the cursor using thumbwheels, mouse, trackball, or the
arrow keys on the keyboard. The user indicates that the cursor has
been positioned by typing any printable ASCII character on the
keyboard. Most control characters (eg, ^C) are intercepted by the
operating system and cannot be used.
- File format
- Binary byte stream. Under Unix, the output may be directed to
a file; under VMS, this is not possible: the output device must
be a terminal.
