Information contained herein is preliminary and subject to change without further notice
 Once the DTE receives the READY indication, the text message must be sent,
terminated by a carriage return.
 The length of the text message entered in this way is limited only by maximum
mobile-originated SBD message length of 1960 bytes.
 The mobile originated buffer will be empty upon power-up.
 If any data is currently in the mobile originated buffer, it will be overwritten.
Command Response:
For the “AT+SBDWT” form:
0 SBD message successfully written to the 9601.
1 SBD message write timeout. An insufficient number of bytes were
transferred to 9601 during the transfer period of 60 seconds.
For the “AT+SBDWT=<text message>” form:
OK: SBD message successfully stored in mobile originated buffer.
ERROR: An error occurred storing SBD message in mobile originated buffer.
2.32 +SBDRT –Short Burst Data: Read a Text Message from the Module
Exec Command: +SBDRT
This command is used to transfer a text SBD message from the single mobile
terminated buffer in the 9601 to the DTE. This command is similar to +SBDRB but
does not provide a length indicator or checksum. The intent of this command is to
provide a human friendly interface to SBD for demonstrations and application
development. It is expected that most usage of SBD will be with binary messages.
 Once the command is entered, the SBD message in the mobile terminated
buffer is sent out of the port.
 This command is similar to +SBDRB except no length or checksum will be
provided.
 The maximum mobile terminated SBD message length is 1890 bytes.
 The mobile terminated message buffer will be empty upon power-up.
Command Response:
+SBDRT:<CR> {mobile terminated buffer}
