I have asked this question before but I did not get satisfactory replies.
Here goes again.

I have written a C program that uses curses. Without using video libraries
and other complicated procedure, I would want to change text colors:
foreground and background. I will be perfectly happy with 7 colors. I looked
in the MSDOS Encyclopedia, and found Int 10H for video functions. I am not
clear whether or not this is the interrupt routine I should use. Any
suggestions to this effect will be appreciated.

Along the same lines, how do I detect number of lines and columns of a
screen. Note I am not doing any video programming. I have seen programs that
convert your screen to 80x28. My program uses only 25 lines instead of 28.
Where do I look for the number of lines/columns? Is it somewhere stored in the
BIOS area? Thanks a bunch.
