[comp.lang.fortran] CGA graphics instruction set

willis@xroads.UUCP (Raymond Willis) (06/05/90)

We have a Compaq 386, Deskpro, with a monochrome monitor which I 
believe is a CGA High Resolution graphics type monitor.  Does anyone
know where I can obtain the graphics instruction set for this kind
of monitor?

I have written fortran subroutines for graphics terminals having 
Tektronix 4010, Regis, and HPGL graphics (used in Hewlett Packard
plotters) and would like to do the same for this monitor.

We have the CGI graphics routines that come with the Xenix Development
System but they require the calling program be written in C and I
want to write in fortran.  I realize that I could write C subroutines
that call the CGI routines which could be called by my fortran program
but I would rather not do this.
