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.
