R

These switches and this file respond to NORAPM INT 2F broadcasts and

manage power consumption by the radio.  Since each radio has different

characteristics, the parameters and their defaults depend on the radio.  Where

possible, the program senses the radio in use and change its defaults accordingly.

The purpose of these programs is to prevent the radio from causing a switch from

the main battery to the backup battery, respond to NORAPM INT 2F broadcasts,

and provide an environment in which application software does work.
If radios are allowed to run on the backup battery, all power could be drained beĆ

fore shutĆdown could be effected.  This condition would destroy all data in the

DRAM and the PEN*KEY HHC would need reprogramming.  Since this is unacĆ

ceptable, the battery power must be monitored and thresholds established for

each radio for powering them down.
The powerĆdown threshold may be set by the application either through WANĆ

POWER APM, command line switches, or INI file entries, or by default.  Once

the threshold is reached, the radio power is shut down regardless of any current

activity (that is, transmission or reception).  To monitor battery status, the

following System Interface Functions are used:

WANPOWER must respond to NORAPM broadcasts.  The events and their reĆ

sponse are listed below.  The response indicated assumes the current mode as set

by default parameters or by the user who permits the operation.  For example, if

the user tells WANPOWER to never shut down, APMSUSPEND, APMCRITIĆ

CALSUSPEND,  APMUSERSUPEND etc., are not honored.

Event

Response

APMSTANDBY

Not implemented by NORAPM

APMSUSPEND

Honored if received, not conflicting with default, userĆsupplied parameters.

If radio operates, request failed.

APMRESUME

PIAĆtoggle DTR (depending on mode). Other radios to be determined (TBD).

APMCRITICALRESUME

Radio powered up, PIAĆtoggle DTR, other radios TBD.

APMBATLOW

This message should never be received.

APMPWRCHANGE

Ignored.  Battery status is constantly monitored.

APMTIMEUPDATE

Ignored.  WANPOWER runs via constant clock.

APMCRITICALSUSPEND Radio powered off.
APMUSERSTANDBY

Not supported.

APMUSERSUSPEND

PIAĆturns itself off.  (OthersĆTBD)
