AT Commands Reference
4.3.3.13
O, Return to Online Data State
This command returns the g20 from the Command mode to the Online Data mode and issues a CONNECT or CONNECT <text>
result code.
After dialing or answering (atd/ata commands and connect), the phone enters the Online Data mode where it is able to transfer
data, but not to enter AT commands.
The ESC command +++, transfers the phone to the Command mode (able to input AT commands, while preserving the Data
call). The O command returns the phone to the fully Online Data mode (as it was before using the ESC command).
The escape character '+' can be changed using the S2-register.
The time delay between two consecutive "+s" is configured using the S12-register.

+COLP, Connected Line Identification
This command refers to the GSM supplementary service COLP, Connected Line Identification Presentation, which enables a
calling subscriber to get the connected line identity (COL) of the called party after setting up a mobile originated call. The
command enables/disables the presentation of the COL at the terminal. It has no effect on the execution of the supplementary
service COLR in the network.
The ability to present COLP at the terminal is controlled by the network provisions. In GSM, the COLP Read command is
network dependent, and as it queries information from the network, it may not be allowed by networks that do not allow
interrogation of the network.
