message list). Pressing the Reply button opens the new message dialog as described above,
except the destination phone number is filled in already.
Outbox
Tapping on the Outbox button opens the list of sent messages. Otherwise the Outbox
behaves exactly as the Inbox described above. The date and time when a message was sent is
not available for GSM modems.
SMS Configuration
Tapping on the SMS Configuration button opens the SMS configuration dialog. The SMS
Centre address follows the same rules as the recipient's phone number in the New message
dialog. The message validity period parameter is sent to the SMS Centre with each message
sent subsequently and instructs the SMS Centre on how long it should attempt to deliver the
message to the recipient (the SMS Centre may impose an upper limit on the validity period
regardless of the setting).
Note: Only certain discrete validity period values can be sent and thus the
validity period is rounded to the nearest allowed value. The next time the
SMS configuration dialog is opened the rounded value is shown.
The user interface tries to keep the SMS storage location available for a new incoming
message if the Delete oldest message when full checkbox is checked. In this case, when a
new message arrives and the SMS storage becomes full, the oldest received message is
deleted. If any string is entered as the Message Suppression Prefix, then messages beginning
with that string will not be shown in either the Inbox or Outbox. In this way messages
intended for another application running on the same device can be hidden from the user, as
long as those messages begin with the string configured here.
B.2 Power Mode
The power mode of the modem is controlled through the Power menu in the Control Panel
(not through the Wireless WAN user interface).
For CF Card modems, the settings are found under the Devices tab. If the checkbox for a
modem is unchecked then no power is applied to the modem and no driver is loaded (neither
the serial port driver nor the Wireless WAN driver). If the checkbox is checked then power is
applied to the modem and the drivers are loaded when the computer is turned on. Power is
removed from the modem when the computer enters suspend mode.
