1.2.3 Set Font Type
Entry Parameter: AH= 2
AL= 0/1 ; set to large/small font
Return Value: None
void TL_font(int status)
{

regs.h.al = 2;
int86(0x09,&regs,&regs);
}
1.2.4 Get Font Type
Entry Parameter: AH= 3
Return Value: AL= 0/1 ; large/small font
int TL_get_font_type()
{
regs.h.ah = 3;
int86(0x09,&regs,&regs);

}
1.2.5 Set User-Defined Font for All Characters
Entry Parameter: AH= 4
AL= 0/1 ; large/small font
DS:DX ; pointer to the buffer with font data
; ( for large font: buffer size = 16*256 =4096 bytes
; for small font: buffer size = 6*256 =1536 bytes )
Return Value: None
