I have a program for an Ibm called Tgraf which is an emulator for the
P.C. to make it compatible with a Tektronix 4105 terminal, I also have
two tek 4014 emulators, but the problem I wish to solve with any of
them, is how can you tell if the point at a given (x,y) set of
coordinates has been set or not. Granted if writing a graphig program,
or something, I could plot onto an array the size of the screen or
something, and look there, but the main purpose is screen dumping to a
file to be printed later. Now the program has this function, but I have
the terminal connmected to a VAX 8600 running ultrix 2.2 and I need a
way preferably in C to read said points. One of the main purposes is to
dump to a DEC LG02 printer, which I have written a graphics driver, but
I did it with only two pages from the manual. (It was all I could get
hold of!) So if anybody know how to plot a point on an LG02 without
calling at a 1x1 vector, I would appreciate it. As far a the book is
concerned, There are only horizontal and vertical vectors, and lines
of any angle must be plotted as a series of 1x1 vectors. WHOA, I'm
drifting, I should post that seperately. Anyway, any help on the
Tek terminals, (Or since I mentioned it), the LG02 (like hints, or
the source of any halfway descent documentation, the manual sucks.)
would be greatly appriciated.
