sequence, the TA enters online command mode, where it can accept AT commands while
retaining the online connection. To return the TA to online mode from the online
command mode, enter the command
ATO
and press ENTER.

Default: none
Starts TA’s internal configuration utility, which you can then use to customize the TA’s
configuration for your particular application. You must enter the command while in your
communication program’s terminal mode.
