ATO
Switch from command mode to data mode / PPP online mode:
ATO is the corresponding command to the +++ escape sequence: When you
have established a CSD call or a GPRS connection and TA is in command mode,
ATO causes the TA to resume the data or GPRS connection and takes you back
to data mode or PPP online mode.
+++
Switch from data mode to command mode:
This command is only available during a CSD call or a GPRS connection. The
+++ character sequence causes the TA to cancel the data flow over the AT
interface and switch to command mode. This allows you to enter AT commands
while maintaining the data connection to the remote device or, accordingly, the
GPRS connection. To prevent the +++ escape sequence from being
misinterpreted as data, it must be preceded and followed by a pause of at least
1000 ms. The +++ characters must be entered in quick succession, all within
1000 ms.
AT+CBST
Select bearer service type:
AT+CBST= <speed>

=4 2400 bps (V.22bis)
=6 4800 bps (V.32)
=7 9600 bps (V.32)
=14 14400 bps (V.34)

<serv> to TE when a call is being set up.

Setting the value to 1 may lead to connection failure, if the application (e.g.
WinFax) waits for default result code/URC.
At+CRC
Set Cellular Result Codes for incoming call indication:
The command controls whether or not to use the extended format of incoming
call indication.
=0 Disable extended format
=1 Enable extended format
Setting the value to 1 may lead to connection failure, if the application (e.g.
WinFax) waits for default result code/URC.
