Chapter 9 – Data Commands
Using AT Commands During a Data Connection
To use AT Commands during a data connection (e.g. while the product is in online mode), it is necessary either to switch to
offline mode, or to use the +WMUX command to enable Commands / Data multiplexing.
Note: currently the +WMUX command is not supported yet.
Switch From Online to Offline Mode +++
During a circuit data call, the “+++” command can be used to suspend the data call and switch from online mode to
offline mode. The “OK” response is returned when the modem has completed the transition to offline mode and is
ready to accept AT commands.
Note:
The “+++” sequence only works with the
+ICF
command using the following settings:
•
8 data bits, with no parity
•
7 data bits, with even parity
