• Attempt to send the User Message. If the message cannot be sent, or the log is

already active, the User Message is logged.

• Immediately log the User Message

• Route the User Message (contents only) to the SMS Destination Address

• Route the User Message (contents only) to the last phone number of an incoming

SMS message

With the last two options the contents of any incoming SMS messages will be routed to the

serial device.

The Message Disposition is controlled by S-Register 167. The settings are as follows:

• 1 or 2 = Send Message, Log if Send Fails

• 3 = Log Message

• 7 = Route Incoming (Client to LMU) SMS messages to the Aux Serial Port. Route all

User Messages to the SMS Destination Address

• 8 = Route Incoming (Client to LMU) SMS messages to the Aux Serial Port. Route all

User Messages to the last phone number that sent the LMU a message

5.2.2.7 MDT Mode – Message Count Limit

The Message Count Limit for the Aux port is defined by S-169. Unlike the Host Port, the

Aux Port limit does not offer a scaling option and therefore only ranges from 0-255

messages. For example, to send every 10

message received on the Aux Port, you would use:

ATS169=10

To send every 150th message, you would use:

ATS169=150
