AT Terminal
The AT Terminal window allows AT commands to be entered and sent to the modem. In some situations (e.g.
during approval testing) it may be required to enter AT commands. This feature should only be used if one has
a good understanding of the AT command set of the installed WWAN modem.
SMS Menu
SMS (Short Message Service) functions are accessed through the SMS menu. For modems that support a
SIM card, the SIM initialization typically takes longer than the network initialization, resulting in a noticeable
delay before the SMS functions become available.
New
Tapping on the New button opens a dialog for sending a new SMS message. The recipient's phone number (to
be entered in the To: field) can consist of the digits 0 through 9, as well as the * and # characters, optionally
preceded by one + character, indicating an international number (i.e. the country code follows immediately
after the + character).
By checking the Store message in Outbox field a new message can be stored in the Outbox before being sent.
If no storage space is available, or the modem does not support the storage of outgoing messages, then this
check box is disabled.
Inbox
Tapping on the Inbox button opens the list of received messages. Reading 50 messages, for example, from the
SIM can take about 30 seconds. By default the list of messages is sorted with the most recently received
message first. The list can be sorted by any other column by clicking on the corresponding column heading.
