INT 15h, Function AX = 5380h, Subfunction BH = 2Eh: Set Activity Mask
NORAPM
Sets the APM activity masks to detect system idle and determine when to issue a
BIOS system suspend request. A bit set in any register enables the
corresponding activity monitor. Clearing a bit disables the activity monitor.
This
interrupt is a NORAND Proprietary System interface.
On Entry:
AH = 53h
AL = 80h
BH = 2Eh
BL = Activity mask 3 (As defined below)
CH = Activity mask 2 (As defined below)
CL = Activity mask 1 (As defined below)

INT 15h, Function AX = 5380h, Subfunction BH = 2Fh: Set Wakeup Mask
NORAPM
Enables or disables the terminal wakeup method, as specified. The following
methods of terminal wakeup are valid. The bit in BL determines the method of
wakeup.
This interrupt is a NORAND Proprietary System interface.
On Entry:
AH = 53h
AL = 80h
BH = 2Fh
BL = Wakeup mask:
Bit 0 = External charge Ċ must be set to 1
Bit 1 = POD 1 RI
Bit 2 = POD 2 RI
Bit 3 = External modem RI
Bit 4 = PC Card RI
Bit 5 = RealĆtime clock alarm
Bit 6 = Reserved Ċ must be set to 1
Bit 7 = Reserved Ċ must be set to 1
On Return:
Carry = 0
AX = 0
