Gateway Only

In Gateway Only mode you can send and receive SMS gateway messages
through the AirLink device to a local device. SMS messages received by the
AirLink device (inbound) are sent on to the configured local device. Messages
sent by the local device to a configured port on the AirLink device are sent out as
SMSs (outbound) to a remote destination. Essentially, the AirLink device sends
SMS messages between the cellular radio and the connected device.
In Gateway Only mode, you can also send SMS commands provided you include
a password. For more information, see Sending SMS Commands to an AirLink
Device on page 163.
To configure ALEOS for Gateway Only mode and format a Gateway message:
1. In ACEmanager, go to Services > SMS.
