This will inform the modem to answer (ATtention Answer).
When the connection is established, a connect message will be displayed including the connection
speed. Sometimes the information comes together with some miscellaneous information, such as
error correction protocols etc.
NOTE: Make sure the remote peer dials the Data Call number
If the voice number is dialled instead of the data number, or if the modem contains an illegal modem
initialization string, the message
OK
or
NO CARRIER
will be displayed almost immediately.
Try to change the modem initialization string. The modem initialization string mainly used to
configure the remote communication is AT+CBST.
Successful modem initialization strings used by Axell Wireless includes (most common first):
AT+CBST=71,0,1;\Q3
AT+CBST=7,0,1;\Q3
AT+CBST=0,0,1;\Q3
AT+CBST=0,0,1;\Q3
AT+CBST=7,0,3;\Q3
Once the modem initialization string is entered, try again to dial up the OMU. For details on the
different modem initialization strings, please refer to the modem’s user guide.
If the setup is successful, the connect message will be brought up;
CONNECT 9600
This means that an online connection is established to the remote peer. From now on, all characters
typed on the keyboard will end up on the remote peer’s screen. Similarly, all characters typed by the
remote peer will be displayed on the screen.
In the example, the incoming call was
successfully answered, and the remote
user entered the text message.
In order to come back to modem command mode, press +++ (three pluses) rapidly (within one
second).
Receiving
OK
means that the modem is back in command mode.
