The mobile terminated message buffer will be empty upon power-up.
Command Response:
+SBDRT: <CR> {mobile terminated buffer}
A.8.88 +SBDD – Short Burst Data: Clear SBD Message Buffer(s)
Exec Command:
+SBDD[<Delete type>]
This command is used to clear the mobile originated buffer, mobile terminated buffer or both.
The <Delete type> parameter identifies which buffers are cleared.
0: Clear the mobile originated buffer
1: Clear the mobile terminated buffer
2: Clear both the mobile originated and mobile terminated buffers
Using this command or power cycling the phone are the only means by which both
buffers are cleared.
The mobile terminated buffer will be cleared when an SBD session is initiated.
Sending a message from the A3LA-R to the ESS does not clear the mobile originated
buffer.
Reading a message from the A3LA-R does not clear the mobile terminated buffer.
Command Response:
0:
Buffer(s) cleared successfully
1:
An error occurred while clearing the buffer(s)
A.8.89 +SBDC – Short Burst Data: Clear SBD MOMSN
Exec Command:
+SBDC
This command will clear (set to 0) the mobile originated message sequence number (MOMSN)
stored in A3LA-R.
The MOMSN is maintained even after power cycle.
Command Response:
0: The MOMSN was cleared successfully
1: An error occurred while clearing the MOMSN
A.8.90 +SBDS – Short Burst Data: Status
Exec Command:
+SBDS
This command returns current state of the mobile originated and mobile terminated buffers.
Command Response:
+SBDS: <MO flag>, <MOMSN>, <MT flag>, <MTMSN>
where:
<MO flag>: The MO flag indicates the existence of a message in the mobile originated buffer.
The response from the A3LA-R is one of the following numeric codes:
0:
No message in mobile originated buffer
1:
Message in mobile originated buffer
<MOMSN>: The MOMSN identifies the sequence number that will be used during the next
mobile originated SBD session.
<MT Flag>: The MT flag indicates the existence of a message in the mobile terminated buffer.
The response from the A3LA-R is one of the following numeric codes:
0:
No message in mobile terminated buffer
