Summary:

In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version

7.0, using the Hercules graphics adapter in graphics mode, each pixel

maps to only 1 bit in memory. Because there is only 1 bit, that pixel

can only be on or off. In Hercules graphics mode, there is no facility

for attributes such as high-intensity, blinking, reverse, or underline.

In Hercules graphics mode, to obtain blinking, reverse, and underline,

your program must manipulate or turn on and off each pixel.

High-intensity is not possible.

If you put the adapter into Text mode, you can use all of these

attributes freely.
