AT interface and switch to Command mode. This allows you to enter AT
Command while maintaining the data connection to the remote server.
OK
To prevent the +++ escape sequence from being misinterpreted as data, it
should comply to following sequence:
No characters entered for T1 time (1 second)
"+++" characters entered with no characters in between (1 second)
No characters entered for T1 timer (1 second)
