2D Set System Time
Entry Parameter: AH = 2DH
CH = hour (0 - 23)
CL = minute (0 - 59)
DH = second (0 - 59)
Return Value: AL = 0/FFH ; OK/Setting error
Example :
int TS_set_time(int hour,int minute,int second)
{
regs.h.ah = 0x2d;
regs.h.ch = hour;
regs.h.cl = minute;
regs.h.dh = second;
int86(0x21,&regs,&regs);
return((int)regs.h.al);
}
2E Set Alarm Date
Entry Parameter: AH = 2EH
AL = 0 ; disable alarm
1 ; enable alarm everyday
2 ; enable alarm by date
If AL = 2:
CX = year (1980 - 2079)
DH = month (1 - 12)
DL = day (1 - 31)
Return Value: AL = 0/FFH ; OK/Setting error
Example
:
int TS_alarm_date(int status,int year,int month,int day)
{
regs.h.ah = 0x2E;
regs.h.al = (unsigned char)status;
regs.x.cx = year;
regs.h.dh = (unsigned char)month;
regs.h.dl = (unsigned char)day;
int86(0x21,&regs,&regs);
