- Hi, I am wondering if someone can help me with what should be
- an easy problem, I think, but I can't find the answer.
-
- I am interested in using text modes 0-3 with an alternate character
- set. I just bought an MS-DOS book, by the Waite Group assuming that it
- would be good, because I really liked their C- Bible. And it has been
- good, regarding memory management, device drivers, graphic modes and
- other things, but it has said near nothing about text modes with color
- or altering the character set.
-
- For some reason I am under the impression that character 00h-7Fh are
- not alterable, but characters 80h-FFh are alterable. I don't
- know why I have this impression, I just do and it may be completely wrong.
- Could someone straighten me ought, and also explain how one would go
- about changing these, especially in C, but I would appreciate any
- solution.
-
- Also, how is color handled in the text modes. I was given the imprsesion
- that a text lines is 80 bytes. This does not leave room for color, or is
- this latched bit planes like the EGA?
-
- Please someone help, with either a BIOS solution or direct or both.
- Thanks in advance for your help.
