Font is saved in the filenamed DEMO.PAS. To use the font, you must call
interrupt 10h, function 11h, sub-function 10h to load up the font.
The following are the parameter needed to call the function:
AX = 0x1110 (ah = 0x11, al = 0x10)
BH = bytes per character
BL = block to load to. (use 0)
CX = number of character defined by table
DX = starting character value
ES = segment of the table
BP = offset of the table
Notice: You should always upload the character immediately after set
the Video mode. Also you must make sure that page 0 is active.
If it is not call immediately after the video mode set, some
side effects may occur. I had experience some palette errors
my self, when I call this function with out changing video
mode. This doesn't happen all the time, however. But be on
the safe side is the best.
FONT MANIA will supply you with the height of the font. It is defined
by your label name with "_POINTS" added at the end of the string. For
example, if your label reference is call DEMO, then DEMO_POINTS will
represent the byte-per-character of the font (the height of the font).
Set the CX to 256 if you want to upload the whole font. If you want to
only upload part of font. Set CX to whatever number of the character
you want to upload, and set DX to the first character you want to upload.
For example, suppose you want to upload the character 65 to 88,
('A' to 'Z') and the label reference is DEMO. Here are the parameter
needed:
AX = 0x1110;
BH = DEMO_POINTS;
BL = 0;
CX = 24; ( 24 characters to load )
DX = 65; ( first character to load )
ES = FP_SEG(DEMO);
BP = FP_OFF(DEMO);
See below for examples of how to set the registers.

void main(void) {
int i;
struct REGPACK r;
printf("This is font test\n\n");
for (i=0; i<256; i++) {
cprintf(" %c", i);
if (!(i % 32) && (i != 0))
printf("\n");
}
printf("\n\nPress any key to load the font...\n");
getch();
r.r_ax = 3; /* always set video mode first */
intr(0x10, &r);
r.r_ax = 0x1110;
r.r_bx = 0x0e00;
r.r_cx = 256;
r.r_dx = 0;
r.r_es = FP_SEG(TEST);
r.r_bp = FP_OFF(TEST);
intr(0x10, &r);
printf("\nFont loaded\nPress any key...");
getch();

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
