- tek - yet another tek4014 emulator
- copyright 1990 Ronald Florence
-
- This package creates yet another tek4014 emulator. On a
- Xenix system with the CGI package, the Makefile will create
- tek and poly (actually a link). Tek reads tek4014 input and
- outputs it to any CGI device. Poly reads ascii integer or
- floating point xy points. Using the SCO CGI devices, we
- have successfully used tek and poly with a VGA, EGA, and CGA
- display, HP 7470a plotter, Laserjet, Deskjet, Epson
- printers, and a Postscript printer. To use the CGI drivers,
- make sure you have the CGIPATH and CGIDISP or CGIPRNT
- environmental variables declared. Tek and poly also
- recognize and work correctly with a Wyse wy99gt terminal
-
- Command line options:
- Invoked as "tek":
- -w reads Accu-Weather maps
- Invoked as "poly":
- -s read xmin, ymin, xmax, ymax scaling points first
- (default is 4096 x 3120)
- Both:
- -p use plotter or printer device for output
- (default is to use the display device)
- -a preserve aspect ratio
-
- The heart of the code is tekdecode.c, which has been written
- so that simple changes to tek4.h will adapt the emulator to
- devices other than CGI. A tek4.h header file for the
- Hewlett-Packard HP7470a plotter is included as a sample.
- Tekdecode.c has also been successfully adapted to drive an
- Epson printer directly.
